On the Influence of a Glass Slide on the SAR Distribution in Petri Dishes for In Vitro Exposure to 2.45 GHz EM Fields

摘要

In order to investigate possible effects on cultured cells of Electromagnetic (EM) fields in the frequency range typical of mobile communications, a large variety of in vitro exposure systems have been designed and numerically characterized. Important requirements for in vitro experiments comprise a high homogeneity of the Specific Absorption Rate (SAR) distribution [1] and the possibility of performing experiments at SAR levels in the range of the actual safety standards of 2 W/kg [2] to achieve a low temperature rise in the cell monolayers. In this paper, a numerical dosimetric analysis has been carried out through CST Microwave Studio 2009. The homogeneity of the SAR distribution and the coupling of EM fields within the liquid in the presence of a glass slide as support for living cells, has been investigated as a function of the incident field polarization.
