Variations in Peak SAR and Temperature Rise From Cellular Phones Due to Hand Position

A view of a repositioned hand from VariPose showing bone, muscle, and connective tissues. This study is an investigation of the effects of hand position and frequency on SAR and temperature rise due to cellular phone use. The study presents calculations of SAR and temperature rise in both head and hand tissue for a range of frequencies and hand positions.

Flat Phantom

 Validation of Specific Absorption Rate (SAR) Calculation in XFdtd® 6.0.


UniPhantom

1 This example illustrates the ability of XFdtd® 6 to import CAD files, manipulate them, apply sources and make SAR calculations.


SAM Head

thumb_sam_head_efieldSpecific Anthropomorphic Mannequin (SAM) geometry is placed in different orientations relative to the coordinate system to perform SAR calculations.


Patch Antenna in Body
