Abstract

The near fields of electromagnetic radiation systems are calculated by using the Finite-Difference Time-Domain （FD-TD） method. It is proved by the results obtained in this paper that the FD-TD method is useful in this calculation. To verify the correctness and accuracy of this method

several kinds of radiation systems are calculated

including the radiation field with structure-complicated Annular Phased Afray（APA）. The distribution of the radiation fields in the central space are obtained and compared with the experimental results.
