An experimental study on the dependence of local SARs on a human ear during exposure to MW from a cellular telephone

Dependence of specific absorption rates (SARs) on the shapes of a human ear during exposure to microwave from a cellular telephone was experimentally evaluated. The local SARs were measured using an electric-field probe in a head phantom of a plastic cubical shell filled with brain-tissue-simulating liquid. It was shown that the shape of the ear strongly affected the SAR distribution in the human head. It was also shown that the measured SAR distributions agreed well with those obtained by the numerical simulation
