Eigenfunction and eigenmode-spacing statistics in chaotic photonic crystal graphs
Shukai Ma, Thomas M. Antonsen, Steven M. Anlage
The statistical properties of wave chaotic systems of varying dimensionalities and realizations have been studied extensively. These systems are commonly characterized by the stati…
Nonlinear Wave Chaos: Statistics of Second Harmonic Fields
Min Zhou, Edward Ott, Thomas M. Antonsen +1
Concepts from the field of wave chaos have been shown to successfully predict the statistical properties of linear electromagnetic fields in electrically large enclosures. The Rand…

Gabriele Gradoni, Thomas M. Antonsen, Steven M. Anlage +1
In this paper, a statistical model for the coupling of electromagnetic radiation into enclosures through apertures is presented. The model gives a unified picture bridging determin…
Focusing Waves at Arbitrary Locations in a Ray-Chaotic Enclosure Using Time-Reversed Synthetic Sonas
Bo Xiao, Thomas M. Antonsen, Edward Ott +1
Time reversal methods are widely used to achieve wave focusing in acoustics and electromagnetics. A typical time reversal experiment requires that a transmitter be initially presen…

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…

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…
A first-principles model of time-dependent variations in transmission through a fluctuating scattering environment
Jen-Hao Yeh, Thomas M. Antonsen, Edward Ott +1
Fading is the time-dependent variation in transmitted signal strength through a complex medium, due to interference or temporally evolving multipath scattering. In this paper we us…
