Abstract

The invention provides a design method and device of an electromagnetic meta-material unit. The method includes the following steps of S1, establishing a simulating model for a selected electromagnetic meta-material structure; S2, analyzing the influences of design parameters on the features of the electromagnetic meta-material in the simulating model; S3, optimizing the design parameters according to the influences. Compared with the prior art, the method has the advantages that the automatic design method based on the simulating model in combination with parameter analysis for optimizing important parameters and minor parameters in different steps is provided for the situation that the requirements for the features of the meta-material are different in different applications; design timeis greatly shortened compared with artificial experience design, and design efficiency and precision are improved; on the other hand, different optimization selection can be carried out in the methodfor the situation that design precision requirements are different under different scenes, and the design time cost is further reduced compared with other automatic design methods.

Description

technical field [0001] The invention relates to the technical field of electromagnetic metamaterials, in particular to a design method for optimizing material parameters and structural parameters of metamaterials by using an automatic search algorithm. Background technique [0002] Electromagnetic metamaterial is an artificial composite structure or composite material, which exhibits extraordinary physical properties that natural materials do not have, such as negative magnetic permeability, negative permittivity, negative refractive index, etc., through artificially designed microstructures. Electromagnetic metamaterials are widely used, and have broad application prospects in many fields such as smart home, public facilities, transportation and industrial sensors, and will become a new technology with great potential in the future. [0003] In different application scenarios, the requirements for the resonant frequency and electromagnetic properties of metamaterials are di...
