Scattering from a circular dielectric post embedded in a grounded dielectric sheet waveguide

摘要

A systematic method for obtaining the scattered electric field in a grounded dielectric sheet waveguide is presented. It is shown that the point-matching method can be used for an explicit calculation of the integral equation to estimate the scattering from a circular dielectric post embedded in the grounded sheet. The magnitude of the reflection coefficient as a function of dielectric constant is given.
