Davis Team Wins Funding for Wireless Research

Prof. Christopher Davis
Professor Davis and his colleagues are using a photo-thermal technique to measure the micro-degree temperature elevations produced in simulated humans (phantoms) by wireless devices. The deflections of multiple laser beams passing through a transparent phantom placed near the wireless device are measured immediately after it is turned on. This allows very rapid determination of the spatial distribution of absorbed energy in the phantom.
It is hoped that this new technique will replace the current slow measurement methods that use electric field probes scanned by a robotic arm in three dimensions inside absorbing phantoms.
