Paper Abstract

The effects of sweat gland ducts (SGD) on specific absorption rate and temperatures during millimeter wave irradiation of skin were investigated with a high resolution finite differences time domain model consisting of a 30 μm stratum corneum (SC), a 350 μm epidermis, 1000 μm dermis and five SGD (60 μm radius, 300 μm height, 370 μm separation). The source was a WR-10 waveguide irradiating at 94 GHz. Without SGD, specific absorption rate (SAR) and temperature maximum were in the dermis near epidermis. With SGD, a higher SAR maximum was inside SGD in the epidermis while temperature maximum moved to the epidermis/stratumcorneum junction. SGD significantly affected how GHz waves were absorbed in the skin. Implications of these finding in nociceptive research will be discussed as well as other potential medical applications.
