摘要
利用飞机和人体块状模型，研究了飞行员在飞机坐舱中受平面电磁波照射时所处的电磁环境、体内的电磁场分布以及所吸收的电磁能量。使用了时域有限差分法中的局部网格细化技术。在整机模型受电磁波照射时，把机头部分细分４倍，然后，在被细化的子空间中把飞行员模型所在的一部分空间再细化４倍，从而使网格边长达到２．５ｃｍ。由于最终使用的人体模型有较高空间分辨率，使所获结果有一定参考价值。
This paper discussed the EM environment, the EM field distributions and the absorbed energy of the pilot sitting in the cockpit irradiated by the EM plane wave by using the subgriding technique of the Finite Different Time Domain (FD-TD) method and the human body model. The head of aircraft was fined four times while calculating for whole aircraft model irradiated by EM plane wave. Then the pilot's sitting space was fined four times again for the subspace. Finally the cell size of the pilot model was taken 2.5cm.The high spacing resolution ensure the worthy results for reference value.
