Abstract
From the practical point of view, conductive film materials that are thin and flexible are chosen as practical shielding materials, and their shielding effect is studied. In the analysis, the concept of equivalent surface resistivity is applied to the FDTD method. The effectiveness of this method in the analysis of absorbed power of the electromagnetic wave in the human body is investigated. The effectiveness of this method for this type of analysis is confirmed. In addition, the shield effect is quantitatively evaluated in terms of the variation of the surface resistivity of the conductive film. It is shown that a resonance phenomenon occurs when the shield effect varies depending on the distance between the human models. It is observed that in such a situation the electromagnetic wave is concentrated in the front surface of illumination so that a large local SAR appears. © 2000 Scripta Technica, Electron Comm Jpn Pt 1, 83(9): 86–92, 2000
