摘　　要：简单阐述电路模拟吸波材料的吸波原理,提出使用CST电磁仿真软件,通过电抗加载的方式对有源电路模拟吸波材料进行分析的方法。设计一款具有双方环结构的有源电路模拟吸波材料,并使用该方法对其进行分析。仿真结果表明这款吸波材料具有良好的双频吸波特性,通过改变两个方环的加载电阻(即改变PIN管的偏置电流),可改变吸波材料的吸波频率。A brief description of the theory of circuit analogy absorbers is presented. A new analysis way is proposed that CA absorbers can be analyzed using CST simulators with the method of reactive loading. A new active CA absorber with array of double square loops is designed,which is studied by the forementioned analysis way. The numeric results show that the absorber has superior performance of absorbing electromagnetic wave at two frequency bands and the reflectivity frequencies of the structure can be controlled when the loading resistances of the array of double square loops vary , that is, when forward bias currents of PIN diodes vary.
