摘　　要：　用FDTD法分析了介质频率选择表面的频率特性。由Floquet定理建立了周期边界条件。采用单色波斜入射,可以方便地对电场和磁场施加周期边界条件,从而将计算域限制在一个周期结构内。The frequency characteristics of dielectric frequency selective surfaces are studied in the FDTD method. The periodic boundary condition is constructed with Floquet theorem. Illuminating the structure with a combination of sine and cosine excitations by oblique incidence, the periodic boundary condition can be employed conveniently for electric field and magnetic field. Thus the calculation region are restricted in a period structure. A comparison between the results and literature′s ones is made. 
