Complex Gaussianity and spatio-frequential memory effect of random wave processes
Guillaume Bal, Anjali Nair
Wavefield speckle patterns are generated by interference of randomly scattered coherent light. In the weak-coupling regime of the Itô-Schrödinger paraxial model for long-distance w…
Long distance propagation of wave beams in paraxial regime
Guillaume Bal, Anjali Nair
This paper concerns the propagation of high frequency wave-beams in highly turbulent atmospheres. Using a paraxial model of wave propagation, we show in the long-distance weak-coup…
Long distance propagation of light in random media with partially coherent sources
Guillaume Bal, Anjali Nair
Optical beam propagation in random media is characterized by familiar speckle patterns generated by intricate interference effects. Such patterns may be modified and possibly atten…
Complex Gaussianity of long-distance random wave processes
Guillaume Bal, Anjali Nair
Interference of randomly scattered classical waves naturally leads to familiar speckle patterns, where the wave intensity follows an exponential distribution while the wave field i…
