Analysis of electromagnetic absorption in the human head for mobile telephone using the method of moments (MoM) and generalized multipole technique (GMT)

Abstract

A numerically efficient technique combining the method of moments (MoM) and the generalised multipole technique (GMT) is developed to determine the electromagnetic field induced inside biological bodies. A tensor integral equation for the electric field inside the body is derived and solved numerically for various biological models. MoM treats the source and biological bodies, while GMT takes the influence of the smooth dielectric body into account. The results obtained are combined with Green's functions in closed form. A multi system is built using a simulation model of a human head. It is able to measure the electric field and determine the absorbed power, SAR can be determined using the dosimetric assessment system (DASY). Applying special software, it can obtain the form of the harmful emissions.
