Dosimetry of Local Radio Frequency Exposure
Doktorsavhandling, 2006

Finite-difference time-domain (FDTD) is a popular computational electrodynamics modelling technique. It has been widely used, from radar cross section computations through electromagnetic compatibility investigations to modelling of electromagnetic exposure in biological tissues. This thesis is dealing with method development for FDTD modelling of electromagnetic exposure in biological tissues. Realistic models of rats and human head are used to evaluate specific absorption rate (SAR) distribution from electromagnetic field (EM) exposure in the radio frequency (RF) spectrum of mobile phone radiation. A new detailed model of the inner ear labyrinth has been reconstructed from computer tomography (CT) images and inserted into the head model. A new stable subgridding technique has been developed and used in the modelling of local exposure in the inner ear exposed to mobile phone radiation. The evaluations are performed in the context of SAR distributions inside the anatomical models for the two Global System for Mobile Communications (GSM) bands, GSM-900 and GSM-1800.
