摘　　要：逆向反演法是作者提出的一种新的分析分层媒质中电磁场的方法。借助于引人单元场量组这一概念，它具有可以直接构造、推演各分层中场量的解析解、并便于统一编程实现数值计算的特点。本文探讨其在水平电偶极子场源情形下的应用。A new analytic method for the electromagnetic field in stratified media- the Counter Propagation Deduction (CPD) Method has been suggested by the authors, which, by introducing a new conception-the Boundary Originated Set (BOS) of waves, is characterized by constructing or deducing the solutions directly, and can provide the direct mathematic expressions of the fields in an arbitrary layer convenient for numerical evaluation by computer programming. This paper discusses its application in the analysis of the electromagnetic field excited by horizontal electric dipoles.
