FDTD calculation of the SAR induced in the human head by mobile phones $new standards and procedures for the numerical assessment

摘要

This paper focuses on new techniques for the FDTD (finite difference time domain) calculation of the SAR (specific absorption rate) induced by mobile phones in the user's head. The implementation of the assessment and averaging procedure proposed by recent standards (such as IEEE Std C95.3-2002) into the EMPIRE/spl trade/ FDTD field solver is presented. In preparation to define a common standard for the numerical treatment of such problems (IEEE P1529) these procedures are applied to a benchmark example of a standard mobile phone model attached to different phantoms of the human head.
