Coherent backscattering of ultrasound without a source
Eric Larose, Oleg I. Lobkis, Richard L. Weaver
Coherent backscattering is due to constructive interferences of reciprocal paths and leads to an enhancement of the intensity of a multiply scattered field near its source. To obse…
Wavevector resonance in a nonlinear multi-wavespeed chaotic billiard
Alexei Akolzin, Richard L. Weaver
Nonlinear coupling between eigenmodes of a system leads to spectral energy redistribution. For multi-wavespeed chaotic billiards the average coupling strength can exhibit sharp dis…
Classical wave experiments on chaotic scattering
U. Kuhl, H. -J. Stoeckmann, R. Weaver
We review recent research on the transport properties of classical waves through chaotic systems with special emphasis on microwaves and sound waves. Inasmuch as these experiments…
Scattering fidelity in elastodynamics
T. Gorin, T. H. Seligman, R. L. Weaver
The recent introduction of the concept of scattering fidelity, causes us to revisit the experiment by Lobkis and Weaver [Phys. Rev. Lett. 90, 254302 (2003)]. There, the ``distortio…
Generalized Berry Conjecture and mode correlations in chaotic plates
Alexei Akolzin, Richard L. Weaver
We consider a modification of the Berry Conjecture for eigenmode statistics in wave-bearing systems. The eigenmode correlator is conjectured to be proportional to the imaginary par…
Variance of transmitted power in multichannel dissipative ergodic structures invariant under time reversal
Igor Rozhkov, Yan V. Fyodorov, Richard L. Weaver
We use random matrix theory (RMT) to study the first two moments of the wave power transmitted in time reversal invariant systems having ergodic motion. Dissipation is modeled by a…
