THEORY OF RADIALLY STRATIFIED MEDIA. PART I. THE BICONICAL ANTENNA IN A RADIALLY STRATIFIED MEDIUM

Abstract

This research is restricted to radially stratified media with = (r) , = (r), where r is the radial distance in spherical coordinates. In these coordinates Maxwell's equations are still separable if the complex dielectric factor = -i / = of(r) depends only on r. The angular equation is not affected. However, the radial equation is no longer the spherical Bessel equation of the homogeneous case. Its coefficients depend on the ''stratification function'' f(r) and contain additional singularities in the complex r-plane. The biconical antenna is the most general problem that can be encountered; it requires the solution of the complicated radial equation from r=O to r= . The theory, nevertheless, is readily applicable to all electromagnetic problems arising in the presence of such media.
