Abstract: Based upon Floquet's theorem,the method of lines is first applied to the analysis of electromagnetic scattering characteristics from a frequency selective surface (FSS) with multilayered dielectric substrates. The formulation is suitable to the FSS with arbitrarily-Shaped elements. Numerical results are in agreement with the experimental data,which verifies the validity of this technique.
