An efficient iterative method for solving quasi-static electromagnetic field problems is presented. The electromagnetic field is generated by an inductive applicator and is represented as a superposition of two constituents, viz. a primary field in absence of the tissue configuration and a secondary field generated by the presence of the tissue. Then, for the secondary field a quasi-static approximation is employed. In the quasi-static field equations a relaxation function is introduced, such that the resulting equations can be solved iteratively. For a realistic three-dimensional model of a human hand numerical results are presented.
提出了一种求解准静态电磁场问题的高效迭代方法。电磁场由感应施加器产生，并表示为两个分量的叠加，即不存在组织构型时的一次场和由组织存在而产生的二次场。然后，对二次场采用准静态近似。在准静态场方程中引入了一个松弛函数，使得所得方程可以迭代求解。针对人手中的实际三维模型给出了数值结果。
