Abstract

The invention discloses a terahertz composite metamaterial multi-band absorber and a design method of the terahertz composite metamaterial multi-band absorber. A terahertz composite metamaterial multi-band absorber comprises a metal base on which is arranged a In the dielectric layer, a metal square ring is arranged above the medium layer, a metal cross is arranged at the inner center of the metal square ring, and a metal circular ring is also arranged between the metal cross and the metal square ring. The invention solves the problems existing in the prior art that the traditional metamaterial absorber design process requires continuous trial and error, case-by-case calculation and analysis, and at the same time requires the designer to have previous simulation experience and metamaterial-related professional knowledge and other limitations. .

Description

technical field [0001] The invention belongs to the technical field of terahertz metamaterials and machine learning, in particular 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 arrangement of subwavelength structural units. They have attracted much attention because they can achieve electromagnetic properties that traditional natural materials do not have. They can provide a unique platform to freely control electromagnetic waves. To meet the designer's application needs. Well-designed metamaterials enable 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, so researchers have carried out a lot of res...
