Abstract
This paper aims at introducing a calibration procedure for experimental dosimetry in a millimeter wave reverberation chamber. The proposed procedure is based on surface temperature measurements performed on a parallelepiped phantom using an infrared camera. The temperature rise measurement is compared to the value predicted by an analytical model. The latter is based on heat transfer formulation using the statistically homogeneous and isotropic electromagnetic field generated in the reverberation chamber. Temperature measurements are performed, at 59.3 GHz, on a dielectric phantom constituted of distilled water with a concentration of 4% of agar. Good agreement is observed between experimental and theoretical models. The difference between the peak specific absorption rate values estimated by two different approaches is about 16%.
