Abstract

A GTEM cell, suitable for assessing possible biological effects induced on cell samples by electromagnetic fields at the typical frequencies of GSM mobile phones, has been designed and set up. Basic environmental requirements for in-vitro biological experiments, involving a GTEM cell, have been assessed by controlling the electromagnetic field distribution and survival conditions. The GTEM cell has been characterized by Standing Wave Ratio (SWR) and Time Domain Reflectometry (TDR) measurements. The impedance matching at the terminal load section has been optimized by considering different hybridload configurations. Moreover, optimal exposure conditions for the biological sample have been experimentally evaluated by paying special attention to the E-field scenario inside the GTEM cell at 900 MHz and 1800 MHz frequencies. At last, an experimental evaluation of the Specific Absorption Rate (SAR) is reported.
