Abstract

In this paper, we present a formulation to analyze the electromagnetic propagation in circular structures filled with complex materials. We consider an uniaxially anisotropy to describes each layer of a stratified cylindrical waveguide. A perfectly matched layer (PML) is used to compute the fields of unbounded waveguides. The mode excitation from an electric current source combined with the mode matching technique (MMT) allows to analyze the propagation through axial discontinuities at the junction between two radially stratified waveguides. Preliminary results are presented.
