Abstract (in Japanese) (See Japanese page) 
(in English) The human body loss was calculated from 2 GHz to 300 GHz using the finite integral and ray
trace methods, and the shielding loss was found to be about 10 dB higher for the human body than for the PEC, especially in the 300 GHz band when the relative permittivity of the PEC and human body were placed in a 200 mm sphere. Furthermore, a model using an actual human body was evaluated. Finally, the shielding loss from the center of the human body was evaluated, and it was found that there was almost no effect of clothing in the 2 GHz, 28 GHz and 100 GHz bands, but there was a clear difference in the 300 GHz band.
