摘要
本文讨论了用FD TD分析FSS的有关问题,提出了一种适合于在任意入射角情况下分析FSS的有效吸收边界条件,分别以单层、双层FSS为例进行了计算.数值结果和矢量模式法、谱域法的结果非常一致.
The application of the Finite-Difference Time-Domain (FD-TD) technique to the Frequency Selective Surface ( FSS)analysis is discussed in this paper. An effective absorbing boundary condition is introduced for arbitrary incidence angle. Some numerical results are given. The numerical results are in good agreement with those by vector mode method and spectral domain method.
