摘要

本文提出了一种基于多层电阻膜的超带宽超材料吸波体的设计模型.该吸波体的结构单元由一种环形电阻膜片在含导体底面的平面分层介质基板上多层叠加而成，各层电阻膜片的外形相同，但表面阻值不同.一件四层吸波体的仿真分析结果表明：该吸波体对6.8GHz～59.6GHz频段之间的垂直入射波吸波率均大于90%；同时对入射角为45度的TE和TM斜入射波仍能保持超宽带吸波，具有极化不敏感和宽入射角特性.另外，对不同层次吸波体的分析表明：随着电阻膜片层次的增加，其吸波效果更好，吸波频带变宽，带内吸波效果更稳定.

Abstract

A novel design approach for creating an ultra-broad-band metamaterial absorber based on multilayer resistance films is provided in this paper.One unit cell of the absorber is composed of multilayer resistance films nipped between layered medium with a metal backboard.The resistance films at different layers are isomorphic

while their surface resistances are unequal.Simulated results of one four-layer absorber shown that the absorber has high absorptivity of more than 90% from 6.9 to 59.6 GHz at vertical incidence

it is polarization-insensitive and angle-wide and can keep strong absorption at TE or TM incidence when the oblique angle of incidence is 45.In addition

the simulated results of several absorbers with different layer indicated that their absorption would be stronger along with the augment of their layers

and the absorption band is wider at the same time.
