Embodiment Construction

[0023] The invention provides a magnetic resonance metamaterial, which has a special resonance effect compared with existing materials and known metamaterials.

[0024] Such as figure 1 As shown, the magnetic resonance metamaterial includes at least one substrate 1 with uniform thickness. A substance that can connect the two is filled between them, such as a liquid substrate material, which will bond the existing two substrates 1 after solidification, so that multiple substrates 1 form a whole. The substrate 1 can be made of FR-4, F4b, CEM1, CEM3 and TP-1 high dielectric constant ceramic materials.

[0025] Virtually divide each substrate 1 into a plurality of identical cubic substrate units next to each other, and these substrate units take one direction (x direction) as a row, and another direction perpendicular to it (y direction) as Arranged in an array in sequence. The side length of the substrate unit is usually between one-fifth and one-tenth of the wavelength of the...

Abstract

An artificial microstructure is provided in the invention. The artificial microstructure includes a first metal line and a second metal line. Said first metal line is a helix which extends outwards helically starting from a central point, said second metal line extends parallel to the first metal line, and said second metal line is connected to the first metal line only at the outermost end of the helix formed by the first metal line. The artificial microstructure of the invention can increase the length of the metal line arranged in the same volume, and then can increase the value of the equivalent capacitance and reduce the resonance frequency, which is advantages to realize the highly integration and avoid or reach certain special frequency band, thus realizing the magnetic resonance function which the existing metamaterial can not realize. In addition, a magnetic resonance metamaterial including said artificial microstructure is provided in the invention.

Description

technical field [0001] The invention relates to the field of metamaterials, more specifically, to a magnetic resonance metamaterial. Background technique [0002] Resonance means that when the excitation frequency of the circuit is equal to the natural frequency of the circuit, the amplitude of the electromagnetic oscillation of the circuit will reach its peak value. A circuit composed of an inductor L and a capacitor C that can resonate at one or several frequencies is collectively called a resonant circuit. In electronics and radio engineering, it is often necessary to select the electrical signals we need from many electrical signals, and at the same time suppress or filter out the electrical signals we do not need. For this reason, a selection circuit is required, that is, a resonant circuit. . On the other hand, in power engineering, there is the possibility of certain hazards such as overvoltage or overcurrent due to the occurrence of resonance in the circuit. There...
