摘要: 本文用時(shí)域有限差分法和人體非均勻電磁模型研究了通過無限大導(dǎo)電壁上窗口透入的電磁場(chǎng)與人體的相互作用。首先對(duì)平面電磁波通過導(dǎo)電壁上窗口的透入特性進(jìn)行了計(jì)算,并與解析解進(jìn)行比較,證明了計(jì)算的可靠性。在此基礎(chǔ)上對(duì)不同極化情況的入射平面波的透入場(chǎng)與靠近窗口的坐姿人體模型的作用進(jìn)行了研究。計(jì)算了人體模型中的電磁場(chǎng)分布和所吸收的電磁能量。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.
