The CGM and the FDTD for SAR studies [PDF]
Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 2002 In the study of electromagnetic radiation effects over dielectric bodies, effective numerical methods are needed. At present, there is a lack of tools for measuring these effects and due to the huge growth of microwave devices, like cellular radio telephones working close to the human body, it is necessary to develop accurate numerical methods for ...
