摘要: 介电型电磁波吸收体的无反射曲线一直是设计高性能吸波材料的重要依据。但传统的无反射曲线仅仅可用于单层材料,无法实现谐振型电磁波吸收体的设计。通过对λ/4型电磁波吸收体理论研究发现:λ/4型电磁波吸收体也可建立起无反射曲线。其特性与表面电阻等参数相关,且更为普适,是传统无反射曲线的扩展,而传统的无反射曲线演化为只是它的一个特例(R=∞),两种无反射曲线可以相互转变。新理论为先进电磁波吸收体的制备提供了更为广阔的设计空间。

Abstract: High pevfornace absorber has been designed according to EMW-absorber non-reflection curve.But traditional non-reflection curve is suitable for monolayer absorber,not for resonance absorbers.Theoretical research on λ/4 absorber manifests that non-reflection curve can also be established for resonance absorber.The characteristics of the curve are related to resistance value.It is more universal and makes the traditional curve a special case(R=∞).The two kinds of curves can be transformed to each other.This new theory provides reference for the design of advanced EMW-absorbers.
