摘要: 本文用时域有限差分法和人体非均匀电磁模型研究了通过无限大导电壁上窗口透入的电磁场与人体的相互作用。首先对平面电磁波通过导电壁上窗口的透入特性进行了计算,并与解析解进行比较,证明了计算的可靠性。在此基础上对不同极化情况的入射平面波的透入场与靠近窗口的坐姿人体模型的作用进行了研究。计算了人体模型中的电磁场分布和所吸收的电磁能量。Abstract: The interaction of human body with penetrated electromagnetic fields through aperture in conducting surface is considered by using the finite-difference time-domain method and inhomogeneous man models. First, the characteristic of penetrated electromagnetic fields through aperture is studied. The comparison of obtained results with those by use of analytical method shows that the method used in this paper is available. The contributions of electromagnetic fields and absorption energy in human body are calculated when the aperture is irradiated by plane wave and the electromagnetic man model in sitting posture is placed to other side of the surface near the aperture for different polarization and frequency of incident place wave.
