Abstract :
A simplified method for measuring the specific absorption rate (SAR) is required in order to limit the spatial-average SAR for mobile devices in Japan. In this paper, a simplified SAR measurement method involving the use of a flat-plane lightweight phantom composed of a radio wave absorber is proposed. The utility of the lightweight phantom and the feasibility of using the proposed measurement method along with the lightweight phantom are verified. Finally, the peak spatial-average SAR is estimated by using the proposed measurement method.
