Fully Symmetric Guided Electromagnetic Waves in a Shielded Plane Dielectric Slab

Аннотация

Paper introduces a concept of fully symmetric guided electromagnetic waves. The waves are considered in a plane dielectric slab shielded with infinitely conducting walls. The permittivity of the slab is given by a real diagonal tensor; the permeability is a constant scalar quantity. This concept includes particular cases of transverse-electric and transverse-magnetic guided waves as well as novel (more complicated) types of guided waves. The dispersion equation is found and studied. A discussion of possible ways to develop the suggested concept is also given.
