Effects on the Resonant Frequencies Caused by Loading a Spherical Cavity with a Dielectric Sphere.

Abstract

An extensive investigation has been carried out of the properties of a conducting spherical cavity filled with a lossless homogeneous dielectric and concentrically loaded with another lossless homogeneous dielectric. This report contains a portion of the results obtained in the course of this investigation. Also presented and discussed are the effects on the cavity system eigenvalues of changing the radius of the dielectric load sphere. This is done for a wide range of relative dielectric strength for the media within the cavity. Specifically, results for relative strengths of 3, 10, and 1/3 are given. The appropriate derivations of the eigenvalue equations are presented. Analysis of the results suggests a broad variety of practical applications. Keywords: Resonant frequency; Dielectric loading.
