We describe theoretically the phenomenon of large-scale incoherent shock within the general framework of the wave turbulence formalism. The wave turbulence theory has been shown to provide a natural asymptotic closure of the hierarchy of moment equations for a system of weakly nonlinear dispersive … See more A nonlocal nonlinearity is found in several systems (dipolar Bose–Einstein condensates26, roton excitations in superfluids28, atomic vapours23, nematic liquid crystals12,18, … See more The formation of shock waves is known to require a strong nonlinear interaction24,33,34,35,36,37,38,39,40,41,42,43,44,45, that is, the initial random wave, , is such that , where and refer … See more We performed a series of experiments that provide evidence of both regimes of incoherent shocks and dispersive shocklets by varying the effective range of nonlocality in the … See more WebSep 17, 2013 · An approach is presented for numerically simulating incoherent imaging using coherent wave optics propagation methods. The approach employs averaging of irradiance from uncorrelated coherent waves to produce incoherent results.

WebApr 14, 2024 · Abstract. Up to now, the generation of X-rays via laser-electron interaction has been presented as well as the fundamentals of scalar wave theory including free-space propagation. However, in most scientific cases X-rays are employed as a diagnostic tool to gain insight into material properties which requires understanding the interactions of X ... http://www-personal.umich.edu/~borcea/Publications/WAVEG_TRANSP.pdf edhrec kelsien the plague

The incoherent wave is modeled by the random uctuations of the acoustic pressure, which dominate the expectation at long ranges from the source. We use the existing theory of wave propagation in random waveguides to analyze the inverse problem of estimating the source from incoherent wave recordings at remote arrays. connect govee to google home
