| 摘 要： | 从麦克斯韦方程组出发,将生物体中的电磁场视为入射场与散射场的迭加,引入极化电流的概念,导出了电磁波在人体中散射的矢量积分方程。利用矩量法将矢量积分方程化为矩阵方程,取脉冲函数为基函数,δ函数为检验函数,求内积得3N 维的复系数线性方程组。对于 N=82的人体块模型,在垂直极化与水平极化的频率为80MHz 的入射波条件下,所得计算结果与 GANDHI的实验室结果吻合较好。

| Abstract: | Vector integral seatter eqation of EM wave in human body are deduced
from Maxwell's Equations,introducing the concept of polarized current and
considering the whole EM field as the sum of induced field and the scatter-
ing field.An 82-cell block model of man is used to calculate the distribution
of EM field for 80 MHz inducing field of both vertical and horizontal pol-
arizations.Finally matrix equations are solved,the distribution of EM fie-
ld in the human body is obtained.The results of calculations agree well
with Gandhi's experiments. |
