Estimation of Transmitted Power Density from Temperature Experiment for EMF Exposure Assessment at 60 GHz

This study aims to develop an experimental approach to estimate the transmitted power density inside human body for dosimetry study of millimeter wave exposure. We developed a temperature measurement system comprised of a millimeter wave generation apparatus at 60 GHz, a semi-solid glycerin phantom and an infrared camera. Based on this system, an estimation method of transmitted power densities was proposed by analyzing the temporal trend of temperature elevation on phantom surface. The validity of the proposed method was confirmed for the case of using a standard horn, and some results of using multi-element patch array antennas were demonstrated.
