Wave Propagation through Axially-Symmetric Dielectric Shells.
Abstract
Section 1 describes a technique estimating the amplitude and phase of guided waves excited on finite dielectric slabs by incident plane waves. The procedure is based on the moment method, but it extends that method by postulating an explicit form for the guided waves and solving for the guided wave amplitudes. The method solves for the two guided waves that travel in opposite directions parallel to the slab. Experiment verified the technique. Section 2 describes nearfield scattering by a finite, solid, dielectric cylinder. Incidence was broadside. The procedure extends the theory originally developed by Richmond. It identifies the effects from the ends of the cylinder. Experiment verified the procedure for polarization parallel or perpendicular to the cylinder. Section 3 describes a new technique for nearfield scattering by a hollow dielectric cylinder. The moment method was used but the cells were finite angular sectors. This is a new shape. Singularities of integrands were integrable. Experiment verified our approximate theory, especially when a correction for the pattern of the probe antenna was utilized.
