Abstract

A full-wave transverse transfer matrix method have been used for analysis of cylindrical and rectangular hollow center waveguides with multilayered coating. The complex modes of leaky-wave character have been investigated in such waveguides with lossy materials filling the covering. The dispersion equations for investigated structures have been introduced and solved in the complex plane region and the propagation and attenuation constants have been obtained. Using this technique the numerical synthesis of the optimal coating profile have been performed. The wide-band, band-path, and narrow-band mode self-filtration, and the possibility of reduction of the dominant mode propagation constant are considered. In this paper the complex permittivities and permeability are neither restricted by any conditions, and nor associated with concrete materials, and the main goal is the synthesis of permittivity and permeability distribution, which are most fitted to our purposes. For example, such coatings may be implemented using composite and artificial materials by means of ion implantation or other technique.
