The edge switch transformation in microwave networks
Vitalii Yunko, Małgorzata Białous, Leszek Sirko
We investigated the spectra of resonances of four-vertex microwave networks simulating both quantum graphs with preserved and with partially violated time-reversal invariance befor…
How T-invariance violation leads to an enhanced backscattering with increasing openness of a wave-chaotic system
Malgorzata Bialous, Barbara Dietz, Leszek Sirko
We report on the experimental investigation of the dependence of the elastic enhancement, i.e., enhancement of scattering in backward direction over scattering in other directions…
Experimental investigation of distributions of the off-diagonal elements of the scattering and the Wigner's matrices for networks with broken time reversal invariance
Michał Ławniczak, Bart van Tiggelen, Leszek Sirko
We present an extensive experimental study of the distributions of the real and imaginary parts of the off-diagonal elements of the scattering matrix and the Wigner's reac…
Hearing Euler characteristic of graphs
Michał Ławniczak, Pavel Kurasov, Szymon Bauch +3
The Euler characteristic and the total length are the most important topological and geometrical characteristics of a metric graph. Here, and …
