Abstract

An efficient hybrid technique, which combines the eigenfunction expansion method (EEM) and the method of moments (MoM), has been developed to critically assess the electromagnetic interactions between handset antennas and a human head, especially the effects of very thin layers (e.g skin) and high frequencies (e.g. 30 GHz). The developed technique is based on the exact scattering solution of infinitesimal dipoles in the presence of a multi-layered, lossy dielectric spherical head. This technique allows to simulate a variety of antennas or antenna arrays. This paper presents mathematical formulations of the technique, validation tests together with results of antenna-head interactions at 900 MHz and 30 GHz.
