Novel specific absorption rate (SAR) measurement system using flat-plane solid phantom

Abstract

In this paper, the required dimensions of the flat-plane solid phantom are derived using the finite difference time domain (FDTD) method to obtain detailed SAR measurements that are equivalent to standardized procedures using the liquid. The proposed measurement system using the flat-plane solid phantom constructed using ceramic materials is presented and the system is validated by acquiring SAR distributions at 900 MHz for two types of antennas.
