[0055] Topological insulator circuits possess multi-dimensional current and voltage control capabilities. By analogizing circuit elements with different topological properties with theoretical models from condensed matter physics, they can achieve waveguiding effects along specified paths for voltage or current waves, or convergence at specified locations. Furthermore, topological insulator circuits are topologically protected, effectively immunizing against backscattering caused by structural defects and disorder, enabling efficient and low-loss wave manipulation.

[0056] Traditional SSH topological insulator circuit design approaches are typically based on relevant theoretical models in condensed matter physics, integrating cutting-edge advances from multiple disciplines to achieve analog implementations of electrical structures. In these implemented circuits, the capacitance or inductance between circuit nodes is adjusted using the node voltage method to open the electrical crystal band gap and achieve energy splitting and topological phase transitions. However, traditional topological insulator circuit designs can only achieve an SSH topological distribution of potential or voltage—that is, voltage is concentrated at the circuit boundaries. This severely limits the practical applications of SSH topological insulator circuits. This is because fields such as wireless energy transmission and magnetic resonance imaging require an SSH current distribution—current concentration at the circuit boundaries, exhibiting a specific distribution or enhancement. Furthermore, voltage-induced effects, such as localized hot spots and discharges, must be suppressed to meet practical application requirements.

[0057] Based on this, the present application provides a method, apparatus, device, storage medium and program product for determining circuit parameters, which determine the circuit parameters of a topological insulator circuit by correlating potential energy with the circuit parameters of the topological insulator circuit, so as to achieve a specific distribution or enhancement of the current in the topological insulator circuit.

[0058] Figure 1 This is a schematic diagram of a topological insulator circuit provided in an embodiment of the present application. The technical solution provided in this application can be applied to Figure 1 The topological insulator circuit shown in FIG. Specifically, as Figure 1 As shown, the topological insulator circuit includes multiple inductors L v , multiple inductors L w And multiple capacitors 2C, multiple inductors L v , multiple inductors L w And multiple capacitors 2C form multiple first closed loops and multiple second closed loops, and adjacent first closed loops and second closed loops share an inductor. It should be noted that, Figure 1 The topological insulator circuit shown can be a circuit in a wireless charging system or a circuit in a magnetic resonance system, and this application does not limit this.

[0059] Figure 2 FIG. 1 is a flow chart showing a method for determining circuit parameters provided by an embodiment of the present application. Figure 2 As shown, the specific steps include:

[0060] S101. Obtain a pre-built circuit model of a topological insulator circuit.

[0061] The topological insulator circuit includes a plurality of first closed loops and a second closed loop.

[0062] S102: Determine the in-situ energy of the first closed loop and the in-situ energy of the second closed loop according to the circuit model, the coupling strength of the first closed loop and the coupling strength of the second closed loop.

[0063] S103. Determine circuit parameters of the topological insulator circuit based on the in-situ energy of the first closed loop and the in-situ energy of the second closed loop.

[0064] In the technical solution provided in the present application, the in-position energy of the first closed loop and the in-position energy of the second closed loop are determined by the circuit model of the topological insulator circuit, the coupling strength of the first closed loop in the topological insulator circuit, and the coupling strength of the second closed loop. Further, based on the in-position energy of the first closed loop and the in-position energy of the second closed loop, the circuit parameters of the topological insulator circuit are determined. By the correlation between the in-position energy and the current, the determined current parameters can achieve a specific distribution or enhancement of the current.

[0065] Each step is explained in detail below.

[0066] S101. Obtain a pre-built circuit model of a topological insulator circuit.

[0067] The topological insulator circuit includes a plurality of first closed loops and a second closed loop.

[0068] In some embodiments, a circuit model for a topological insulator circuit is constructed based on the loop current method. The loop current method, also known as the mesh current method, is a classic method for analyzing current distribution in circuits, particularly for planar circuits. The loop current method is based on Kirchhoff's voltage law (KVL), which assumes that the sum of all voltages in a closed loop is zero.

[0069] S102: Determine the in-situ energy of the first closed loop and the in-situ energy of the second closed loop according to the circuit model, the coupling strength of the first closed loop and the coupling strength of the second closed loop.

[0070] Among them, the coupling strength of the quasiparticle in the first closed loop is also called the coupling strength of the first closed loop, the coupling strength of the quasiparticle in the second closed loop is also called the coupling strength of the second closed loop, the in-position energy of the quasiparticle in the first closed loop is also called the in-position energy of the first closed loop, and the in-position energy of the quasiparticle in the second closed loop is also called the in-position energy of the second closed loop.

[0071] S103. Determine circuit parameters of the topological insulator circuit based on the in-situ energy of the first closed loop and the in-situ energy of the second closed loop.

[0072] The circuit parameters of the topological insulator circuit include at least one of the following: the inductance of the first closed loop, the capacitance of the first closed loop, the inductance of the second closed loop, and the capacitance of the second closed loop.

[0073] In some embodiments, as Figure 3 As shown, a circuit model of a topological insulator circuit is pre-built, including the following steps:

[0074] S201 . For each closed loop in the topological insulator circuit, obtain a loop model of the closed loop under preset conditions.

[0075] The preset condition is that the algebraic sum of the component voltages in the closed loop is zero.

[0076] It should be noted that according to the theory of the SSH model, the key to realizing one-dimensional topological boundary states lies in the transition strength between periodically arranged particles. If a classical linear electronic circuit needs to simulate the SSH model, it needs to pass inductors and capacitors to imitate a similar relationship. Figure 1 A schematic diagram of a circuit structure provided in this application is shown in FIG. Figure 1 As shown, there are two inductors L in the circuit. v and L w Periodic arrangement to achieve mesh current I i The simulation of the coupling strength between Figure 1 In the circuit shown, the mesh represents the current loop, through Figure 1 The circular arrow in the figure shows the I in the circular arrow. i Characterize the i-th mesh and the corresponding current loop. Adjacent current loops share an inductor L in the structure. v or L w , inductance will directly affect the coupling strength between network currents.

[0077] In some embodiments, a circuit model for a topological insulator circuit is constructed based on the loop current method. The loop current method, also known as the mesh current method, is a classic method for analyzing current distribution in circuits, particularly for planar circuits. The loop current method is based on Kirchhoff's voltage law (KVL), which assumes that the sum of all voltages in a closed loop is zero.

[0078] Based on this, this application constructs a circuit model of a topological insulator circuit based on the loop current method. Specifically, for each closed loop in the topological insulator circuit, Kirchhoff's voltage law is applied to control the algebraic sum of the voltages of the components in the closed loop to be zero, which is the preset condition in this application. The resistance and voltage in the closed loop are determined by Ohm's law: V = IR. And in Figure 1In a circuit, a resistor shared by two adjacent closed loops is affected by the currents in both adjacent closed loops. Each closed loop can be expressed as a set of equations using Kirchhoff's voltage law. The number of these sets of equations is equal to the number of closed loops in the topological insulator circuit. These sets of equations are described in this application as circuit models for the closed loops.

[0079] S202: Determine a circuit model based on loop models of multiple closed loops.

[0080] Exemplarily, the circuit models of multiple closed loops are combined to obtain a circuit model of a topological insulator circuit. The circuit model of the topological insulator circuit is as follows:

[0081]

[0082] Among them, Z v is the coupling strength of the quasiparticle in the first closed loop, also known as the coupling strength of the first closed loop, Z w is the coupling strength of the quasiparticle in the second closed loop, also known as the coupling strength of the second closed loop, Z1 is the in-position energy of the quasiparticle in the first closed loop, also known as the in-position energy of the first closed loop, and Z2 is the in-position energy of the quasiparticle in the second closed loop, also known as the in-position energy of the second closed loop.

[0083] In some embodiments, determining the in-situ energy of the first closed loop according to the circuit model, the coupling strength of the first closed loop, and the coupling strength of the second closed loop specifically includes the following steps:

[0084] The in-situ energy of the first closed loop is determined according to the circuit model, the coupling strength of the first closed loop, the coupling strength of the second closed loop, and the first balancing parameter.

[0085] The first balancing parameter is determined according to the angular frequency and capacitance of the topological insulator circuit. Exemplarily, the first in-position energy can be determined according to the following formula:

[0086] Z1=Z v +Z w +2×Z A

[0087]

[0088] In the above formula, Z A is the first balancing parameter, j is a complex number, ω is the angular frequency of the topological insulator circuit, and C is the capacitance of the topological insulator.

[0089] In some embodiments, determining the in-situ energy of the second closed loop according to the circuit model, the coupling strength of the first closed loop, and the coupling strength of the second closed loop specifically includes the following steps:

[0090] The in-situ energy of the second closed loop is determined according to the circuit model, the coupling strength of the first closed loop, the coupling strength of the second closed loop, and the second balancing parameter.

[0091] The second balancing parameter is determined according to the angular frequency and capacitance of the topological insulator circuit. Exemplarily, the second in-position energy can be determined according to the following formula:

[0092] Z2=Z v +Z w +2×Z B

[0093]

[0094] In the above formula, Z B is the first balancing parameter, j is a complex number, ω is the angular frequency of the topological insulator circuit, and C is the capacitance of the topological insulator circuit.

[0095] In some embodiments, such as Figure 4 As shown, determining the circuit parameters of the topological insulator circuit based on the in-situ energy of the first closed loop and the in-situ energy of the second closed loop specifically includes the following steps:

[0096] S301. Obtain the angular frequency, capacitance, and coupling ratio of the topological insulator circuit.

[0097] The coupling ratio is the ratio of the coupling strength of the first closed loop to the coupling strength of the second closed loop.

[0098] It should be noted that in order to ensure that the current in the topological insulator circuit presents an SSH topological distribution, the relevant parameters in the topological insulator circuit should meet the following conditions:

[0099] Z1=Z v +Z w +2×Z A

[0100] Z2=Z v +Z w +2×Z B

[0101] Z1=Z2=0

[0102]

[0103] Z v =jωL v -j / ωC v

[0104] Z w =jωL w -j / ωCw

[0105] Among them, L v is the inductance of the first closed circuit, C v is the capacitance of the first closed circuit, L w is the inductance of the second closed circuit, C w is the capacitance of the second closed circuit. It can be seen that the first balancing parameter Z A and the second trim parameter Z B It is mainly used to ensure that the in-situ energy of the first closed loop is equal to the in-situ energy of the second closed loop, so as to facilitate the calculation of circuit parameters.

[0106] According to the above conditions, it is known that in order to determine the circuit parameters of the topological insulator circuit, the angular frequency of the topological insulator circuit and the capacitance of the topological insulator circuit should be obtained. In addition, in order to ensure that the current in the topological insulator circuit presents the SSH topological distribution and enhances the boundary state characteristics of the topological insulator circuit, by selecting the ratio of the coupling strength of the first closed loop and the coupling strength of the second closed loop, that is, the coupling ratio, it is possible to improve the performance of the topological insulator circuit, and to contribute to realizing that the current presents the SSH topological distribution. Exemplary, in general, the coupling strength of the first closed loop is greater than the coupling strength of the second closed loop. Therefore, the coupling ratio is less than 1. In actual situations, according to the actual test of technical personnel, the coupling ratio is less than 0.5, and the circuit parameters determined can present better effects. For the selection of the coupling ratio, it can be determined according to actual conditions, such as historical experience, related inferences and other methods, and this application is not limited thereto.

[0107] S302. Determine circuit parameters of the topological insulator circuit based on the in-situ energy of the first closed loop, the in-situ energy of the second closed loop, the angular frequency, the capacitance, and the coupling ratio.

[0108] The circuit parameters of the topological insulator circuit include at least one of the following: the inductance of the first closed loop, the capacitance of the first closed loop, the inductance of the second closed loop, and the capacitance of the second closed loop.

[0109] In some embodiments, when the angular frequency, capacitance, and coupling ratio of the topological insulator circuit are obtained, the circuit parameters of the topological insulator circuit are obtained by calculation based on the above conditions.

[0110] Exemplarily, after determining the circuit parameters of the topological insulator circuit, the topological insulator circuit is designed according to the determined circuit parameters through experimental simulation, and the feasibility of the present application is determined through the simulation results.

[0111] In some embodiments, if it is not possible to directly obtain the accurate angular frequency of the topological insulator circuit, the operating frequency of the topological insulator circuit can be first obtained, and then the angular frequency can be determined based on the operating frequency of the topological insulator circuit. Specifically, Figure 5 As shown, the following steps are included:

[0112] S401. Obtain an operating frequency of a topological insulator circuit.

[0113] Exemplarily, the operating frequency of a topological insulator circuit can be determined by system specifications. For example, in filters and modems used in communications equipment, the operating frequency of the topological insulator circuit is determined by the system specifications, and the operating frequency of the topological insulator circuit can be directly obtained from the corresponding system specifications. For another example, if the operating frequency cannot be directly obtained, it can be determined through calculation.

[0114] S402. Determine an angular frequency of the topological insulator circuit based on an operating frequency of the topological insulator circuit.

[0115] Exemplarily, after obtaining the operating frequency of the topological insulator circuit, the angular frequency of the topological insulator circuit can be directly calculated and determined according to the following formula:

[0116] ω=2πf

[0117] Where ω is the angular frequency of the topological insulator circuit, and f is the operating frequency of the topological insulator circuit.

[0118] In this way, determining the operating frequency of the topological insulator circuit by the operating frequency of the topological insulator circuit can effectively improve the accuracy of the angular frequency of the topological insulator circuit and further improve the accuracy of determining the circuit parameters.

[0119] To determine the feasibility of the technical solution of this application, the following example is used. Taking the application of this application to the technical field of magnetic resonance imaging as an example, specifically applying it to a 1.5T magnetic resonance imaging system. The operating frequency f of the magnetic resonance imaging device is obtained to be 64 MHz, and 0.26 is selected as the coupling ratio. The following conditions are solved to determine its circuit parameters:

[0120] Z1=Z v +Z w +2×Z A

[0121] Z2=Z v +Z w +2×Z B

[0122] Z1=Z2=0

[0123]

[0124] Z v =jωL v -j / ωC v

[0125] Z w =jωL w -j / ωC w

[0126] Next, the circuit is designed according to the determined circuit parameters, and the current in the topological insulator circuit is measured by the corresponding test instrument, such as Figure 6 Figure 2 shows the test results of the current in a topological insulator circuit. It can be seen that at 64 MHz, the current exhibits the SSH topological distribution characteristic, with the current intensity concentrated in the initial and terminal loops. Furthermore, the magnetic field of the topological insulator circuit also exhibits the SSH topological distribution characteristic, with the magnetic field concentrated at the circuit's boundaries.

[0127] In addition, the technical solution provided by this application can also achieve long-distance wireless transmission of signals. For example, in the field of magnetic resonance imaging, in situations where it is impossible to see the magnetic resonance image, the technical solution provided by this application can now make it possible to see the corresponding image.

[0128] In some embodiments, to obtain more accurate circuit parameters, after determining the circuit parameters, the capacitance value can be repeatedly adjusted through simulation to determine multiple sets of circuit parameters, and then the most accurate circuit parameters can be selected as the actual circuit parameters. Since there is a certain logical relationship between the capacitance and circuit parameters of the topological insulator circuit, in actual application, the determined circuit parameters can be optimized by continuously adjusting the capacitance value to ensure that the circuit parameters can realize the topological distribution characteristics of the current and improve the presentation effect of the circuit parameters.

[0129] In the technical solution provided in the present application, the in-position energy of the first closed loop and the in-position energy of the second closed loop are determined by the circuit model of the topological insulator circuit, the coupling strength of the first closed loop in the topological insulator circuit, and the coupling strength of the second closed loop. Further, based on the in-position energy of the first closed loop and the in-position energy of the second closed loop, the circuit parameters of the topological insulator circuit are determined. By the correlation between the in-position energy and the current, the determined current parameters can achieve a specific distribution or enhancement of the current.
