Abstract
Presents finite-difference time-domain (FDTD) calculations of the specific energy absorption rate (SAR) in a fine-scaled, heterogeneous, realistic model of the head for frequencies ranging from 600 MHz to 3 GHz. The phantom has been derived from an atlas of cross-sectional anatomy. The cell size is 3.2 mm which results in a 120000 cell head model comprising brain, bone/fat, muscle, skin, blood, air and eye humour, lens, and sclera. Irradiation from the front and side for plane-wave exposure of an adult and an infant are considered.
