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.
