Abstract

The phenomenon of electromagnetic scattering from a thin dielectric sheet is investigated by combining the impedance sheet approach and the method of moments (MoM). In general, the impedance used in an MoM-approximate boundary condition is the resistive impedance Z_L. However, in the literature, four different impedance expressions have been derived and summarized. These include the above resistive impedance Z_L, the more general resistive impedance Z_O, the surface impedance Z_V or Z_H, and the connection impedance Z_s. It is found that the surface impedance is optimal for computing the reflection and scattering from a thin dielectric sheet. The radar cross section (RCS) is computed and compared between the MoM-approximate boundary condition and the analytical approaches, viz., the generalized Rayleigh-Gans (GRG) and physical optics (PO) methods.
