CALCULATION OF WHOLE-BODY SAR FROM A 100 MHZ DIPOLE ANTENNA

By M. Zhang and A. Alden

Full Article PDF (625 KB)

Abstract:
This paper presents results of a dosimetry study at an FM broadcasting frequency of 100 MHz. The work focused on SAR calculations with high resolution Magnetic Resonance Imaging (MRI)-based full-body models. FDTD computer modeling used a half-wave dipole as the exposure source. Extensive calculations give the variation of SAR with distance and show that whole-body average SAR exhibits a different distance dependency from the incident power density. Body size has a significant effect on SAR. Based on the numerical results, an empirical formula was developed to describe the relationship between antenna input power and distance for the limiting SAR value.
