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…
An Ultrasonic analog for a laser
Richard L Weaver, Oleg I Lobkis, Alexey Yamilov
We report measurements on ultrasonic systems analogous to random lasers. One system entails unstable ultrasonic feedback between distinct transducers, another involves a piezoelect…
Non-exponential Dissipation in a Lossy Elastodynamic Billiard, Comparison with Porter-Thomas and Random Matrix Predictions
Oleg I. Lobkis, Igor S. Rozhkov, Richard L. Weaver
We study the dissipation of diffuse ultrasonic energy in a reverberant body coupled to a waveguide, an analog for a mesoscopic electron in a quantum dot. A simple model predicts a…
