Parabolic equation method for electromagnetic guiding structures

Abstract

In order to demonstrate the versatility and computational efficiency of the numerical parabolic wave equation (PE) approach, we present a number of examples from different branches of applied electromagnetics: UHF radiowave propagation over irregular terrain, full-wave 3D simulation of VHF radio communication in a curved tunnel, optical propagation in a rough dielectric slab, and wave fields in tapered waveguides. An important application of the PE techniques has been found in numerical modeling of the imaging performance of X-ray Fresnel microlenses (zone plates).
