Computation of the internal electric field induced in the human body by low-frequency power systems is time-consuming. We compute an approximate solution in nearly real time by using a reduced basis for the internal field. The basis is computed once (off-line) by approximating the source by multipoles, the coefficients of which can be computed for any position of the human body due to analytic translation and rotation formulas. The results are validated with respect of finite element method (FEM) computation.

使用多极点的低频电磁场实时数值剂量法

低频电源系统在人体中感应的内部电场的计算非常耗时。我们通过对内部场使用简化的基础来近似实时地计算近似解。通过多极点近似源，可以一次（离线）计算基础，由于解析平移和旋转公式，可以针对人体的任何位置计算其系数。相对于有限元方法（FEM）计算，对结果进行了验证。
