The output of a GSM900 test mobile phone was connected by coaxial cable to a TEM cell which has been described previously in the reference article. In principle, this is a spliced coaxial cable with a central electrode and an outer shield electrode with the unique characteristic of having both linearamplitude and phase response versus frequency and allowing relatively homogeneous exposures of samples.
Rats were not restrained during exposure inside the TEM cell. The power of the test phone was kept constant at 33 dBm (2 W) and monitored online using a power meter.
Sham exposures were performed in the same TEM cell with MW power off. The order of four independent MW and sham exposures was randomized among sessions on four consecutive days.
The SAR value was determined both by measurements and by calculations: Incident, reflected and transmitted powers were measured for an input power of 1 W using a power meter and a coaxial directional coupler. The absorbed power was then calculated and the average whole body SAR was determined showing very small variations of average whole body SAR for rats of different sizes. Numerical calculations were performed using the FDTD method. The SAR in the brains of rats was found to vary less than four-fold from the average value of 0.4 mW/g in the numerical rat shaped phantom at different positions inside the TEM cell. The calculated SAR values were in good agreement with the measured ones.
