Closed Parallel-Plate Chiral Waveguides with Boundary Impedance Conditions

摘要

The paper discusses electromagnetic wave propagation in chiral slab waveguidesthat are characterized by surface impedances of different types. The method applied makes use of the vector circuit theory and the related tangential field requirements on the slab surfaces. The method forms a coherent and solid approach to waveguide analysis since all cases considered can be solved from the same general eigenvalue equation. The paper consists of two parts: the brief derivation of the general equation and its application to different chiral waveguides. The calculated curves support the theoretical analysis.
