Heating of rat skin by high power millimeter waves

Air Force Research Laboratory published the non-lethal Millimeter wave weapon “Active Denial System” (ADS). Because of the thermal shallow penetration induced by its high frequency, the penetration depth is always less than 1mm. Heat gathers at the skin surface, caused the strong thermal effect on the skin. We built up a transient thermal multilayer model for heating of human skin by high power millimeter waves by finite volume method (FVM) based on Pennes´ bioheat transfer equation in this paper. The transient temperature distributions of the cross-section profiles were calculated, and we analyzed the calculated results and compared them with the experimental ones. The veracity and reliability of finite volume model were validated. This model provides the theoretical basis for the study of the inverse problem of Active Denial System (ADS).
