摘要
Abstract
To study the relation between the EM property and shielding efficiency of shielding material, the whole body averaged SAR and organ SARs of the shielding human model have been calculated using FDTD, the effects of different frequencies and different incidence angles have been studied too. The results show the whole body averaged SAR decreases with the improvement of shielding efficiency of shielding material. Because of the EM leakage of neckline, cuff and other openings, the whole body averaged SAR doesn't change obviously after it declines to a certain extent. Partial shielding method has the good shielding effect on the shielded organs. Compared with horizontal irradiation, the whole body averaged SAR increases substantially when being irradiated upward, and decreases when being irradiated downward.关键词
