Abstract

In the case of far filed exposure to human body, whole body resonance phenomena arise in VHF frequency band when the component of E-field is parallel to the human body´s height. In this phenomenon intensive induced current is observed in the human body. In this paper, in order to analyze this phenomenon with high accuracy by using FDTD method. We propose an efficient modeling method to model half space ground plane by using Surface Impedance boundary condition(SIBC) and quasi static filed distribution.
