- Abstract
Transverse Electromagnetic Mode (TEM) cell is an expanded planar transmission line operated in the TEM mode to simulate a free space plane wave. Present work aimed at the characterisation of a TEM cell model IFI-CC104SEXX in the frequency band 600 MHz - 1.2 GHz for controlled exposure of liquid samples. Bioelectromagnetic experiments need proper dosimetric assessment and this can be done by using a TEM cell. The sample (water) was exposed inside the cell at continuous wave with input powers of 190 mW - 19W and the specific absorption rate of energy (SAR) was determined. Obtained SAR vales were in the limits 0.1-2.6 W/kg enabling low- and medium-power radiofrequency exposure. Calibration curves were obtained for the empty cell and efficiency calculations of absorbed energy in the sample were made. Results indicate the feasibility of using this TEM cell model for further biological effects investigation due to controlled exposure of the specimen.
