Internal distribution of the local SAR in the human abdomen measured by a split phantom and small helical antennas at 150 MHz
Description
The purpose of this paper is to analyze and measure the internal SAR (specific absorption rate) distribution in a human abdomen created by portable radio terminal antennas at 150 MHz. To this end, we have developed a unique phantom that can be split into two pieces in the longitudinal direction along its center. A thermographic technique is used for the SAR measurement in the cut plane of the phantom. An analytical approach involving thermal analysis using the finite element method was conducted in conjunction with EM analysis by FDTD to estimate the cooling effects that occur by thermal diffusion in the phantom after exposure to EM energy.
