用时域有限差分法和非均匀块状人体电磁模型研究了脉冲电磁场对人体的作用问题。首先用解析法计算无限长介质圆柱中脉冲波所引发的电流以验证计算方法,然后对核电磁脉冲照射下的二维和三维非均匀块状人体模型中产生的电流及所吸收的电磁能量进行了研究,计算了它们随时间的变化及其在全身的分布,在计算中没有考虑介质色散的影响。
The interaction of the pulse electromagnetic field with human body using the Finite-Difference Time- Domain(FD-TD) method and the inhomogeneous block human body model is discussed in this paper. To verify the validity of the method
the first step is calculation of the currents induced in the infinite long dielectric circular cylinder expoused to pulse EM wave. Then the currents induced in 2D and 3D inhomogeneous block human body models under the expouse of unclear EM pulse are calculated. The current versus time and the current distributionof the whole body model are calculated too. The influence of the medium dispersion isn’ t considered
it’ s a further research problem.
