energy absorbed in the head when illuminated by communicationsenabled
personal data assistant (PDA)-type devices. We study the
relative changes in specific absorption rates in the head due to perturbing
metallic rings in proximity to the face illuminated by a
1.8 GHz dipole and a monopole on a conducting box. Simple and
complex head models used in a validated finite-difference time-domain
(FDTD) simulation are compared with measurements from
an industry standard DASY4 SAR measurement system. Both simulation
and measurement are referred to the IEEE specific anthropomorphic
mannequin head. Results show that metallic rings may
alter specific absorption rates (SAR) level distributions within the
head. Results are given for several common ring sizes.
