Abstract

This paper presents finite-different time-domain (FDTD) calculations of the specific absorption rate (SAR) averaged over the mass of the eye, and over 1 g and 100 g of tissue in a realistic model of the head from a closely coupled half-wavelength dipole source. The SAR is predicted as a function of the separation between the vertical dipole and the surface of the eye. The feed point of the dipole is on the axis defined by the centre of the eye. Phantoms representing an adult and a one-year-old child have been considered for irradiation at 900 MHz and 1.9 GHz.
