A kind of metamaterial resonant frequency testing device and testing method

Abstract

The invention provides a metamaterial resonant frequency testing device and testing method. The resonant frequency of a metamaterial can be accurately tested, detection on parameters and characters of metamaterial products is achieved, a testing method can be provided for the application of the metamaterial, and accordingly the research, development and design efficiency of the metamaterial is improved.

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...

AI Technical Summary

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
