Abstract(in English) | It is well known that electromagnetic (EM) energy is absorbed in-homogeneously in the human body even for far-field exposure. This implies that local resonance for various individual organs occurs. In order to investigate this implication, we analyzed numerically the organ resonance characteristics in the frequency range from 30 MHz 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 and the resonance around 200 MHz due to the horizontal dimensions of body cause the local resonance for almost all the organs at the same frequencies. Local resonance peculiar to each of organs was also found to occur around 700 - 900 MHz, and the specific absorption rate (SAR) levels were higher than that at the whole-body resonance frequency for brain, eyes and testicles. In addition, we also investigated the influence of human height and weight on the SAR around the resonance frequencies, and found that a thinner body would have a higher SAR level. |
