| Abstract(in English) | In this report, the compensation techniques for thermal diffusion in the SAR measurement using the thermographic method are proposed. We have investigated the SAR measurement by the thermographic method using the solid phantom above 3 GHz up to now. Calculations using the FD-TD method and the heat transfer equation are carried out to evaluate the thermal diffusion during the measurement by the thermographic method. As a result, the thermal diffusion influences the SAR evaluation at 5 GHz band even though this method basically does not depend on the frequency. In this time, a proposal for the compensation in the temperature rise distribution including the influence of the thermal diffusion is made by use of a compensation coefficient deduced from the temporal transition of the temperature rise due to the electromagnetic radiation in an observation point. |
