摘要

众所周知，即使在平面波照射下，人体对电磁能量的吸收也是不均匀的。这意味着不同个体器官可能发生局部共振。为了研究这一含义，我们利用基于解剖学的高精度人体模型和并行时域有限差分(FDTD)技术，对30 MHz至3 GHz频率范围内的器官共振特性进行了数值分析。结果，我们发现发生在65 MHz左右的全身共振会导致所有器官在同一频率上产生局部共振。每个器官特有的局部共振也被发现发生在大脑、眼睛和心脏的900千兆赫左右，睾丸等的600兆赫左右。

FDTD calculation of organ resonance characteristics in an anatomically based human model for plane-wave exposure

It is well known that electromagnetic (EM) energy is absorbed inhomogeneously in the human body even for plane-wave exposure. This implies that local resonance for various individual organs may occur. In order to investigate this implication, we analyzed numerically the organ resonance characteristics in the frequency range from 30 MHz up to 3 GHz with an anatomically based high-precision human body model and a parallel finite-difference time-domain (FDTD) technique. As a result, we found that the whole-body resonance occurring around 65 MHz causes the local resonance for all the organs at the same frequency. Local resonance peculiar to each of organs was also found to occur around 900 GHz for the brain, eyes and heart, 600 MHz for the testicles, and so on.
