Abstract

A novel iteration procedure of a hybrid method combining the method of moments (MoM) and the finite-difference time-domain (FDTD) method is adopted to simulate the interactions between human head and linear antenna. Not only are the near-filed distributions in human head presented but also the disturbed far-field patterns of the antenna. The results obtained by the hybrid method are compared with those by the software FEKO. There is a good agreement between them.
