Abstract :
Using a hybrid method of moments/finite difference time domain technique, a study of the effects of human proximity on the polarisation purify of circularly-polarised handset antennas for personal satellite communications was undertaken. Assessments of specific absorption rate in the head were also made. The method gave stable results, in accordance with physical expectations. Good agreement with the pure method of moments was shown in simplified cases
