Radiophysics and Quantum Electronics Aims and scope

Abstract

The effect of boundary irregularity on the ELF field in a waveguide is studied by the full-wave/ray method using the focusing-factor equation. The displacement of the normal-wave trajectories into the complex region and the field along them are estimated, and the applicability conditions of a longitudinal approximation of field phase and amplitude in a two-dimensionally irregular waveguide are determined. The transverse scale of an inhomogeneity that changes the qualitative dependence of the field on distance is found.
