Abstract

Several wireless communication technologies operating in the millimeter wave (MMW) band are already in practical use. Therefore, a safety analysis of exposure to MMW frequency is required. In this study, we measured dielectric properties of epidermis and dermis at up to 110 GHz using enucleated porcine skin, because of measurement data scarcity for biological tissues in the MMW band. The Measurement results were compared with literature values. Furthermore, a numerical dosimetry study was conducted using a 2D forearm model, and localized energy absorption inside the forearm was evaluated. The frequency dependence of energy absorption obtained from the dielectric property measurements is compared with that obtained from literature.
