| Abstract(in English) | Dielectric properties for human-body tissues are indispensable for dosimetry evaluation in humans for electromagnetic field exposure, while they are being derived from in-vitro measurement data by Gabriel. In this study, we have measured complex relative permittivities for skin tissues of palm and sole for two subjects in the frequency range from 100MHz to 40GHz by using a commercially available open-ended coaxial probe, and have compared the results with the Gabriel in-vitro measurement data. As a result, we found that in comparison with the Gabriel data, the real and imaginary parts of measured complex relative permittivities are lower by 20-87% for palm and sole, and by 13-92% for palm, respectively, while the imaginary parts for sole are not always lower and depend on the subjects. The above findings obtained suggest that unlike in-vitro measurement data, in-vivo measurement data for complex relative permittivities of skin tissues can be strongly affected by secretions from sweat glands. |
