本文用试射法求解铁磁媒质中一维非线性正弦电磁场问题,比用差分法的精度高,并且省去了差分法中每次迭代都要求解一个大型方程组的过程。
In this paper, the problem of one-dimensional nonlinear sinusoidal electromagnetic field in ferromagnetic media is solved by test-firing method. Compared with the difference method, the accuracy of the method is high, and the process of solving a large system of equations for each iteration in the difference method is eliminated.
