| 内容記述 | The propagation characteristic of the electromagnetic wave to the human head is examined in frequency 3.35 GHz. Human head is designed as the layered structures such as skin, fat, bone, Dura, CSF (Cerebrospinal fluid) and brain. EM wave Radiation and Electric filed propagation are numerically examined by FDTD (finite different time domain) method of two dimensional Maxwell's equation. For 2D FDTD, E polarization case of Transverse magnetic (TM) mode are implemented with Matlab programming. The electric field point source is kept near cylindrical human head and then analyze the nature of wave propagation to the tissue layer by layer using the impedance mismatch and specific absorption rate (SAR). Only some part of head that located near the source has the high level of E field absorption rate and then it sharply decreases. The electric field absorption rate reach peak in Skin and CSF layer. This paper also mentions the relationship between the rising of SAR rate and the reflection rate at each tissue layer interface. | |||||
