A Comparison of Exact Versus Perturbed Pole Locations of Dielectric Objects in Dielectric Medium
Abstract
The dielectric properties of soils and plastic targets are given. The approach for finding exact pole locations from a dielectric infinite slab, a dielectric sphere, and a dielectric infinite cylinder is presented (and applied). The exact poles for the slab and sphere are found for various sizes and dielectric properties. There is a discussion (and use) of Carl E. Baum's perturbation formulas for dielectric slabs and spheres. George Hanson's results (formulas, from using Carl's same approach) are given (and used) for an infinite dielectric cylinder. The poles found from the perturbation formulas are compared with the exact poles and an "effective" region for using the perturbation formulas is established.
