Problems solved by technology

[0004] In the prior art, the simulation calculation of the resonant frequency of metamaterials can be realized by means of 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. Simultaneously, due to the difference in manufacturing process, there is an error between the simulation result and the actual metamaterial resonant frequency

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a testing technology for the resonance 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 possess. Through the structurally ordered design of materials at key physical scales, it is possible to break through the limitations of certain apparent natural laws, thereby obtaining metamaterial functions beyond the ordinary properties inherent in nature. The properties and functions of metamaterials are mainly derived from their internal structures rather than the materials that compose them. Therefore, a lot of research work has been carried out 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 open-loop ...
