Characterization of a GTEM cell designed for the SAR evaluation in in vitro experiments

In this paper we propose a new version of the GTEM cell suitable for in vitro experiments. It is a valid dosimetric site because the cell can assume properly reduced sizes in order to be included in a commercial incubator necessary to allow the survivor of the biological sample under test. Moreover, the electromagnetic field inside the GTEM cell can be accurately monitored and controlled in order to guarantee a uniform distribution near to the sample under test. We have experimentally verified the feasibility of the first preliminary GTEM cell prototype as dosimetric site by measuring the SAR of a distillate water sample and the experiment result has been validated by the corresponding value numerically calculated by a dedicated homemade computer code based on the method of moments and on the resonance transverse diffraction method. Finally, the SAR calculation of a brain cell sample in the GTEM cell is reported.
