Impedance and Scattering Variance Ratios of Complicated Wave Scattering Systems in the Low Loss Regime
Jen-Hao Yeh, Zachary Drikas, Jesus Gil Gil +6
Random matrix theory (RMT) successfully predicts universal statistical properties of complicated wave scattering systems in the semiclassical limit, while the random coupling model…
Nonlinear Time-Reversal of Classical Waves: Experiment and Model
Matthew Frazier, Biniyam Taddese, Bo Xiao +3
We consider time-reversal of electromagnetic waves in a closed, wave-chaotic system containing a discrete, passive, harmonic-generating nonlinearity. An experimental system is cons…
Quantifying Volume Changing Perturbations in a Wave Chaotic System
Biniyam Tesfaye Taddese, Gabriele Gradoni, Franco Moglie +3
A sensor was developed to quantitatively measure perturbations which change the volume of a wave chaotic cavity while leaving its shape intact. The sensors work in the time domain…
Mitigating the effect of non-uniform loss on time reversal mirrors
Biniyam Tesfaye Taddese, Thomas M. Antonsen, Edward Ott +1
Time reversal mirrors work perfectly only for lossless wave propagation. Here, the performance of time-reversal mirrors is quantitatively defined, and the adverse effect of dissipa…
Nonlinear Time-Reversal in a Wave Chaotic System
Matthew Frazier, Biniyam Taddese, Thomas Antonsen +1
Exploiting the time-reversal invariance and reciprocal properties of the lossless wave equation enables elegantly simple solutions to complex wave-scattering problems, and is embod…
Iterative Time Reversal with Tunable Convergence
Biniyam Tesfaye Taddese, Thomas M. Antonsen, Edward Ott +1
We propose and test an iterative technique for improving the temporal focusing of a time reversal mirror. A single amplification parameter is introduced to tune the convergence of…
Sensing Small Changes in a Wave Chaotic Scattering System
Biniyam Tesfaye Taddese, Thomas M. Antonsen, Edward Ott +1
Classical analogs of the quantum mechanical concepts of the Loschmidt Echo and quantum fidelity are developed with the goal of detecting small perturbations in a closed wave chaoti…
Sensor Based on Extending the Concept of Fidelity to Classical Waves
Biniyam Tesfaye Taddese, James Hart, Thomas M. Antonsen +2
We propose and demonstrate a remote sensor scheme by applying the quantum mechanical concept of fidelity loss to classical waves. The sensor makes explicit use of time-reversal inv…
