PROPAGATION IN A MONOCLINIC PERIODIC MEDIUM

Propagation of electromagnetic waves in a three-dimensional periodic medium with monoclinic lattice structure is analyzed from a transmission-line viewpoint. It is shown that the problem can be treated by the method of coupled transmission lines. From an eigenvalue formulation one obtains the propagation constants for the various eigenmodes of the structure. These are shown to be Bloch type waves and their propagation constants are pure, real or imaginary, just as for a lossless periodic structure in a waveguide.
