Problems solved by technology

[0004] In the prior art, the simulation and calculation of the resonant frequency of metamaterials can be realized through computer simulation, but there is a problem that, for metamaterials with complex microstructure arrays, it takes a long time even if a high-performance computer is used. At the same time, due to the difference in the manufacturing process, there is a large error between the simulation results and the actual metamaterial resonance frequency, which brings great difficulties to the practical application of metamaterials.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a testing technique for the resonant frequency of metamaterials. 【Background technique】 [0002] Metamaterials refer to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, the limitation of some apparent natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary nature inherent in nature. The properties and functions of metamaterials mainly come from their internal structures rather than the materials that make them up, so a lot of research work has been done to design and synthesize metamaterials. In 2000, Smith et al. of the University of California pointed out that the composite structure of periodically arranged metal wires and split-ring resonators (SRR) can real...
