✦ Synopsis

The human living environment is mostly surrounded by buildings. This paper assumes the corner of a structure, and presents a model analysis for a human body standing close to a right-angled corner, examining the SAR characteristics for TM and TE microwaves. In the microwave range, the three-dimensional model calculation is difficult because the length of the human body is large compared to the wavelength. A two-dimensional cylinder and an elliptic cylinder are therefore used as the human model. The wholebody average SAR obtained from the two-dimensional cylinder model is compared to the already known realistic model presented for the TM resonance frequency range, and the applicable range of the two-dimensional cylinder model is investigated. Based on the result, the frequency characteristics of the whole-body average SAR are investigated for various model positions and incidence angles. For 1 GHz, the result is compared to the case of the elliptical cylinder model. The local SAR distributions are also shown. It is seen that the whole-body average SAR can sometimes be as large as 10 times the case without a corner at a frequency below 1 GHz.
