Use of a block hand phantom for mobile phone specific absorption rate measurements

Recent studies have shown when using a mobile phone in the talk position, the spatially averaged Specific Absorption Rate (psSAR) inside the head may increase due to the hand. As a result, the use of an anatomically correct hand phantom has already been proposed for psSAR compliance testing. This pa...
