Abstract

The scattering of electromagnetic waves by an homogenous isotropic dielectric shapes has been investigated using a quasistatic approximation. In this study, the modified Rayleigh-Gans approach is developed and applied to a circular thin disc, rod, and sphere whose physical sizes are small compared to wavelength. The scattered field relationships are used to obtain the radar cross section equations in closed form and also normalized absorption and scattering cross sections computed by using internal fields
