Information transfer through disordered media by diffuse waves.
We consider the information content h of a scalar multiple-scattered, diffuse wave field psi(r) and the information capacity C of a communication channel that employs diffuse waves to transfer the information through a disordered medium. Both h and C are shown to be directly related to the mesoscopic correlations between the values of psi(r) at different positions r in space, arising due to the...
متن کاملShock waves in disordered media.
We experimentally investigate the interplay between spatial shock waves and the degree of disorder during nonlinear optical propagation in a thermal defocusing medium. We characterize the way the shock point is affected by the amount of disorder and scales with wave amplitude. Evidence for the existence of a phase diagram in terms of nonlinearity and amount of randomness is reported. The result...
متن کاملPropagation of nonlinear waves in disordered media
We study the propagation of stationary waves in disordered non-linear media described by the nonlinear Schrödinger equation and show that for given boundary conditions and a given coherent wave incident on the sample, the number of solutions of the equation increases exponentially with sample size. We also discuss the ballistic case, the sensitivity of the solutions to the change of external pa...
متن کاملInformation transfer in disordered media by broadband time-reversal: stability, resolution and capacity
We analyse rigorously the time reversal of a multiple-input-multiple-output system in a strongly fluctuating disordered medium described by the stochastic Schrödinger equation with a random potential under the sub-Gaussian assumption. We prove that in a broadband limit the conditions for stable super-resolution are the packing condition such that the spacing among the N transmitters and M recei...
متن کاملAmplitude coda of classical waves in disordered media.
The propagation of classical waves in the presence of a disordered medium is studied. We consider wave pulses containing a broad range of frequencies in terms of the configurationally averaged Green function of the system. Damped oscillations in the time-dependent response trailing behind the direct arrival of the pulse (coda) are predicted, the periods of which are governed by the density of s...
