| Abstract: | In this paper, the electromagnetic scattering by a periodic triangular structure on a thin dielectric sheet is studied. With a view to facilitate design, the expression of equivalent susceptances are given. The numerical results of transmission coefficients and equivalent susceptances are presented. The numerical results show that the equivalent susceptances appear to be inductive or capacitive accordingly while the polarization of the plane wave is perperdicular or parallel. |
