Abstract: The electromagnetic energy provided by the space solar power station will be high-power, the charged devices will re-excite different-frequency electromagnetic waves in the charging process, then producing a certain threat to human health. For the low-frequency electromagnetic waves, the whole human body can be equivalent to a simple model to analyze the impact of electromagnetic waves on human health. However, as the frequency increases to GHz, the wavelength becomes comparable to the dimensions of local human tissues so that a realistic human body model has to be used to get the more accurate analyses of the related effects. Therefore, this study focuses on SAR analyses for the 58GHz which based on a real arm model. The plane wave is used to illuminate the real arm model, consequently study the SAR values on the arms surface as well as the in-arm SAR values penetrating into various critical local regions in order to provide references for impact analyses of high-frequency scenarios.
