Abstract

The invention discloses a terahertz composite metamaterial multi-band absorber and a design method of the terahertz composite metamaterial multi-band absorber. The terahertz composite metamaterial multi-band absorber comprises a metal substrate, a dielectric layer is arranged on the metal substrate, and a metal square ring is arranged above the dielectric layer. A metal cross is arranged in the center of the interior of the metal square ring, and a metal circular ring is further arranged between the metal cross and the metal square ring. According to the present invention, the problems that in the prior art, in the design process of a traditional metamaterial absorber, continuous trial and error and case-by-case calculation and analysis need to be carried out, and meanwhile designers need to have previous analog simulation experiences and professional knowledge related to metamaterials, are solved.

Description

technical field [0001] The invention belongs to the technical field of terahertz metamaterials and machine learning, and specifically relates to a terahertz composite metamaterial multi-band absorber, and the invention also relates to a design method of a terahertz composite metamaterial multi-band absorber. Background technique [0002] Metamaterials are artificial composite electromagnetic materials composed of periodic arrangements of subwavelength structural units. They have attracted much attention because they can realize electromagnetic properties that traditional natural materials do not have. It can provide a unique platform to freely control electromagnetic waves. To meet the application needs of designers. Well-designed metamaterials can achieve many exotic functions, such as: holography, perfect absorption, tunability, etc. [0003] The design process of metamaterials is very complex and requires a lot of time and computing resources. Therefore, researchers have...
