Microwave transport experiments have been performed in a quasi-two-dimensional resonator with randomly distributed conical scatterers. At high frequencies, the flow shows branching structures similar to those observed in stationary imaging of electron flow. Semiclassical simulations confirm that caustics in the ray dynamics are responsible for these structures. At lower frequencies, large deviations from Rayleigh's law for the wave height distribution are observed, which can only partially be…

Experimental observation of a fundamental length scale of waves in random media.

It is shown numerically how the scintillation index can be used to assess the scaling behavior of the branching length, and the scaling range extends much further than expected from random caustics statistics.

Branched flow and caustics in nonlinear waves

Rogue waves, i.e. high amplitude fluctuations in random wave fields, have been studied in several contexts, ranging from optics via acoustics to the propagation of ocean waves. Scattering by

Caustics and Rogue Waves in an Optical Sea

This paper reports a detailed experimental study of linear rogue waves in an optical system, using a spatial light modulator to impose random phase structure on a coherent optical field.

Extreme waves and branching flows in optical media

We address light propagation properties in complex media consisting of random distributions of lenses that have specific focusing properties. We present both analytical and numerical techniques that

Observation of Branched Flow of Light

The evolution of coherent waves in two-dimensional systems with a random potential can give rise to an interesting phenomenon known as Branched Flow. In this process, a wave scatters from a weak

Perfect transmission through Anderson localized systems mediated by a cluster of localized modes.

This study systematically found resonance modes of a 2-D Anderson localized system that allow for the near-perfect energy transmission and observed that the internal field distribution of these eigenchannels exhibit dense clustering of localized modes, which suggests that the clustered resonance modes facilitate long-range energy flow of local waves.



Intensity distribution for waves in disordered media: Deviations from Rayleigh statistics

We study the intensity distribution function $P(I)$ for monochromatic waves propagating in a quasi-one-dimensional disordered medium, assuming that a point source and a point detector are embedded in

Signatures of photon localization

Signatures of photon localization are observed in a constellation of transport phenomena which reflect the transition from diffusive to localized waves. The dimensionless conductance, g, and the

Refraction of a Gaussian seaway

[1] Refraction of a Longuet-Higgins Gaussian sea by random ocean currents creates persistent local variations (in the form of lumps or streaks) in average energy and wave action distributions. These

Shallower regions in the oceans can act as lenses, focusing the energy of tsunamis, typically onto cusp points where two caustic lines meet. Diffraction theory enables calculation of the profile of a

Coherent branched flow in a two-dimensional electron gas

The theoretical study of this flow indicates that this branching of current flux is due to focusing of the electron paths by ripples in the background potential, which may have important implications for a better understanding of electron transport in 2DEGs and for the design of future nanostructure devices.

Intensity Distributions of Waves Transmitted through a Multiple Scattering Medium.

The distributions of the angular transmission coefficient and of the total transmission are calculated for multiple scattered waves. The calculation is based on a mapping to the distribution of

Statistics of branched flow in a weak correlated random potential.

It is shown how such branching arises from caustics in the classical flow and a simple scaling behavior of the branching under variation of the random potential strength is found.

Significance of K Distributions in Scattering Experiments

Evidence is presented which suggests that a class of modified Bessel-function distributions may have special significance in describing the statistics of radiation scattered by media characterized by
