ON THE GREEN-FUNCTIONS TECHNIQUE AND PHASE VELOCITY APPROXIMATION OF AXIALLY SYMMETRIC FIELDS IN STRATIFIED MEDIA

摘要

In this paper a numerical method is developed to solve a one-dimensional inverse scattering problem associated with a pair of two coupled partial differential equations. These equations are for the Green functions that can be used for the optimization of electromagnetic energy within selected regions of a medium in which the propagation is taking place. The method is based upon constructing the Nth degree interpolation polynomial to approximate the Green functions acid the phase velocity function using Legendre-Gauss-Lobatto collocation points. An example is given to demonstrate the accuracy of the developed method. (C) 1996 American Institute of Physics. [References: 14]
