Theory of a periodic cylindrical waveguide with a nonuniform metal-dielectric filling
Abstract
A theory of wave propagation through a screened annular waveguide with a piecewise-continuous fielding is developed. The coupled fields in the dielectric layers are described with the aide of a characteristic matrix. The conditions at the discrete boundary yield a set of functional equations characteristic of the Riemann-Hilbert problem. The propagation constant follows from the condition that the determinantal of the equivalent algebraic set should be equal to zero. Analysis of the field phase and reduced amplitude in a wide range of variation of the waveguide parameters suggests promising performance characteristics of the structure as a prototype mode and spatial spectrum selector.
