MODEL ANALYSIS AND SYNTHESIS OF ELECTROMAGNETIC FIELDS.

Abstract

Electromagnetic radiation and diffraction problems in regions characterized simply in a spherical coordinate system are analyzed from a spherical transmission line viewpoint. The electromagnetic fields are decomposed into E mode and H mode constituents with respect to the radial coordinate, and these separate contribution may in turn be derived from scalar potentials functions, which satisfy the scalar wave equation. Alternative representations for the potentials in terms of transmission along the angular coordinates are presented and their respective virtues discussed. The results are applied to various electromagnetic boundary value problems involving spherical, conical, and wedge-shaped obstacles, and high-frequency asymptotic solutions are derived which permit an interpretation of the field in quasi-optical terms.
