| Experimental investigation of Wigner's reaction matrix for irregular graphs with absorption (2009) | |||||||||
Abstract | |||||||||
| 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.. Comment: 12 pages, 6 figures | |||||||||
