Abstract

This paper proposes a numerical study to simulate the effects of dielectric shield on the specific absorption rate (SAR) and the temperature increase in the human body exposed to leakage microwave energy. In this study, the effects of shield dielectric properties on distributions of SAR and temperature increase within the human body at various operating frequency are systematically investigated. Based on the obtained results, the installed dielectric shield strongly affects the SAR and the temperature increase in human body. The SAR and the temperature increase in human body can be reduced simultaneously by setting the appropriate dielectric properties of the dielectric shield. The appropriate dielectric properties of the dielectric shield greatly depend on the operating frequencies. These fundamental data for the implementations of the radiation protection shielding materials, with focusing on the human organism, are provided as well.
