复杂谐振系统散射参数的计算

Calculating the Scatter Parameter of the Complex Resonant System

计算复杂系统的散射参数，会出现矩阵不满秩，这在ＣＡＤ中导致计算的中断。本文分析了这种奇异的原因，指出这对应于该子网络处于谐振状态，处理该情形的计算方法也一并给出，这种算法在计算机辅助设计中得到了应用。

In calculating the scatter parameter of the complex system,there may be matrix of unfilled rank which results in interruption of the CAD process. This paper analyzes the source of this singularity ,pointing out that such case is corresponding to the resonance of some sub-network. The algorithm to deal with such case is given. This method is applied to the CAD calculation.
