宽带电磁探头是电磁兼容测量中的一个重要器件。对宽带探头进行分析需要求解矩阵方程。对于目前所用的计算电磁学全波方法，当在低频计算的时候，会遇到阻抗矩阵奇异性的问题。针对低频阻抗矩阵奇异性问题，采用奇异值分解的方法求解矩量法方程。对比广义本征值方法，计算仿真分析表明，奇异值分解方法与广义本征值方法一样，可以有效地解决低频奇异性的问题。

Broadband electromagnetic probes are important for electromagnetic compatibility measurement. When the full wave equations are solved at low frequency, the singularity of impedance matrix will be found. In this paper the singular value decomposition method is applied to solve this problem. Compared with the general eigenvalue method, this method can also get the same results. It shows that each one can effectively deal with the singularity problem.
