| Infrared absorbing metamaterials is a kind of based on the theory of absorbing materials with superior physical properties of the design of artificial structure material. This paper based on infrared absorbing metamaterials structure design research the structural parameters of unit(unit type, unit size, etc) and medium parameters (equivalent dielectric constant and equivalent permeability) on its infrared absorption properties, and starting from the direction of the impedance matching absorbing theory and summary discussed the influence factors of the infrared absorbing materials. By the numerical simulation result, has realized the single band dual band and the multichannel infrared absorption in different units, the biggest absorption rate reached99%is the "perfect absorption", for the practical application of the infrared absorbing materials and design to provide theoretical support. |
