FDTD Based SAR Analysis in Human Head using Irregular Volume Averaging Techniques of Different Resolutions at GSM 900 Band



Specific Absorption Rate (SAR) induced inside human head in the near-field of a mobile phone antenna has been investigated for three different SAR resolutions using Finite Difference in Time Domain (FDTD) method at GSM 900 band. Voxel based anthropomorphic human head model consists of different anatomical tissues is used to calculate the peak SAR values averaged over 10-g, 1-g and 0.1-g mass. It is observed that the maximum local SAR increases significantly for smaller mass averages.
