摘要
文章采用谱域法并结合互阻抗法,对低RCS双层FSS天线罩进行了仿真设计,并就多层介质衬底影响下的频率特性进行了分析。与其他方法相比,谱域法能仿真更复杂的FSS单元,求解模型简单,计算量小,能得出非常理想的仿真结果。文章采用这种方法得到的分析结果与实测结果相符合。
In this paper, a Spectral Approach, which combined with Method of Moment, is used to simulate design for low RCS double layers FSS antenna shade and analyze the frequency characteristic of double layers FSS under the condition of the multi - layers dielectric underlay. Compared with other methods, this Spectral Approach can simulate more complicated elements of FSS with less running time. The simulation model is very simple, and the result is accordant with real measuring result.
