Four WPCs were placed into two incubators (one for RF and one for sham exposure using blind procedure). Each WPC was shielded by a 40 x 40 x 20 cm metal grid box and four blocks of foam absorber material (15 dB). The absence of any interference between the two WPCs located in the same incubator was confirmed by measurement.
The WPCs consisted of two parallel plates short-circuited at the edge at four points [Laval et al., 2002]. Four Petri dishes (3.5 cm in diameter) were placed in each WPC, one of them filled only with medium for monitoring temperature. A water spiral plate jacket was positioned on the external faces of both plates of the WPC with circulating water maintaining a temperature of 37 °C in the medium.
The SAR distribution inside the Petri dishes was calculated using a commercial code, solving Maxwell's equations based on the Finite Integral Technique (FIT). In addition, two kinds of measurements were carried out, electric field distribution and SAR. The averaged SAR for each dish was evaluated by the thermal power pulse method [Hand et al., 1989], using four Petri dishes filled with 2 ml of culture medium, a high RF power pulse, and a fluoroptic thermometer measuring thermal increase in five points inside each dish. The spatial distribution of the E-field as well as the efficiency obtained for the system showed a good agreement between measured and calculated values.
