标题： Experimental investigation of Wigner's reaction matrix for irregular graphs with absorption

摘要： 我们使用由同轴电缆和通过T型接头连接的衰减器组成的四面体微波网络，对存在吸收的情况下不规则图的Wigner反应K矩阵进行实验研究。 从每个微波网络实现的散射矩阵S的测量中，我们获得了K的虚部和实部的分布。我们的实验结果与理论预测良好一致。 显示英文摘要

摘要： We use tetrahedral microwave networks consisting of coaxial cables and attenuators connected by T-joints to make an experimental study of Wigner's reaction K matrix for irregular graphs in the presence of absorption. From measurements of the scattering matrix S for each realization of the microwave network we obtain distributions of the imaginary and real parts of K. Our experimental results are in good agreement with theoretical predictions.
