EM FIELDS INSIDE A PROLATE SPHEROID DUE TO A THIN CIRCULAR LOOP: A HIGHER-ORDER PERTURBATION APPROACH

By L. W. Li, M. S. Yeo, and M. S. Leong

Abstract:
This paper presents an alternative analysis of obtaining radiated electromagnetic (EM) fields in a dielectric prolate spheroid using the perturbation technique. A circular loop antenna is used as a radiator on the top of the spheroid. The spheroid is approximated by the first a few terms of the Taylor series expansion (higher-order approximation), and coefficients for transmission and scattered EM fields are found using the perturbation method where the coefficients are also expanded into Taylor series and determined by matching the boundary conditions on the spheroidal dielectric surface. After the approximated coefficients and EM fields are obtained, validity of the approach is discussed and limitations are also addressed.
