Constructing the analytic solutions of the EM fields in spherically stratified media by the counter‐propagation deduction method

Abstract

A new method, the Counter‐Propagation Deduction (CPD) method is applied to deduce the Debye potentials πe and πm which are introduced to express the EM field in a spherically stratified medium. By introducing a new concept, the Boundary Originated Set (BOS) of waves, the CPD method can directly construct the analytic solution of the EM field in an arbitrary layer, which, due to the simplicity of the deduction procedure and the expression, can be easily evaluated numerically, irrespective of the number of the layers.
