Constructing the Analytic Solutions of the Em Field in Cylindrically Stratified Media By the Counter-Propagation Deduction Method

Abstract

_—A new method, the Counter-Propagation Deduction (CPD) method is applied to deduce the E_z and H_z in a cylindrically stratified medium, from which the other components of the E and H can be deduced. By introducing a new concept, the Boundary Originated Sets (BOS), the CPD method can directly construct the analytic solutions, which, due to the simplicity of the deduction procedure and the expressions, can be easily evaluated numerically, irrespective of the number of the layers.
