Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] see figure 1 , an embodiment of the present invention provides a microstrip circuit full-wave analysis method, which includes the following steps:

[0050] Step S1, using the octree data structure to group the divided three-dimensional object models, and enclosing the three-dimensional objects with a cube, the cube being the first and last group node of the zeroth layer, Divide the cube into eight sub-cube nodes to form the first layer of nodes, and then subdivide each sub-cube in the same way as in the previous step, and so on until the electrical size of the bottom cube reaches the required appropriate size until. In this embodiment, the electrical dimension of the bottommost cube is 0.2-0.4 wavelengths of incident waves.

[0051] see figure 2 , for the non-empty subgroup i of layer l, the set of all far-field non-empty ...

Abstract

The invention provides a full wave analysis method for a microstrip circuit based on improved MDA (model driven arthitecture) -SVD (singular value decomposition) compression representation. The method comprises the following steps of establishing an octree structure for a target to be analyzed; acquiring sparse low rank representation which is formed by a discrete electric field integral equation and corresponds to a far field action part in a dense impedance matrix by the MDA-SVD method; then representing the part which is represented by the low rank in the impedance matrix by the improved MDA-SVD method; and finally, constructing an algorithm which quickly calculates matrix vectors and is suitable for iteration computation on the basis of the MDA-SVD method representation. According to the full wave analysis method for the microstrip circuit, on the basis of the traditional MDA-SVD method, a new compressed format is constructed to represent the impedance matrix, so that memory requirements and computation complexity can be effectively reduced, and computation time is shortened.

Description

technical field [0001] The invention relates to a microstrip circuit, in particular to a full-wave analysis method for a microstrip circuit based on an improved MDA-SVD compression representation. Background technique [0002] Microstrip circuits, like microstrip antennas, are widely used in mobile communication, microwave relay communication, radar, navigation, rocket guidance and other fields due to their small size, light weight, low cost, high performance and reliability, etc. Development in the direction of broadband, miniaturization and complex structure. New developments also put forward higher requirements for the design of microstrip circuits. At present, using software simulation to analyze such problems has become an important means of pre-production design. How to efficiently perform fast full-wave electromagnetic analysis and parameter extraction on it in simulation is very important. At present, the simulation analysis methods for microstrip circuits are main...
