WebOct 14, 2024 · We theoretically investigate light scattering from an array of atoms into the guided modes of a waveguide. We observe that the scattering of a plane-wave laser field into the waveguide modes is dramatically enhanced for angles that deviate from the geometric Bragg angle. This modified Bragg condition arises from the dispersive … WebNov 11, 2012 · Assuming a spatially random potential fluctuating in time with a Gaussian white-noise spectrum, they suggested that the root-mean-square displacement of the particle grows with exponent 3/2 in...
WebJan 30, 2002 · The Bragg scattering of random, non-stationary surface gravity waves by random topography on a gently sloping bottom is investigated. A correction is given of previously published expressions for the triad wave–wave–bottom interaction source term in the spectral energy balance equation, and the result is reconciled with Webtask dataset model metric name metric value global rank remove
WebJun 1, 2012 · Another drawback is their inefficient pumping. Since multiple scattering can occur for the photon pump too, the entire random system cannot be pumped uniformly and therefore efficiency would be lower than one expects. So far, some works have been done to make 1D RLs. The first was fabricated by Milner et al. [21]. They used a stack of cover ... WebNov 10, 2011 · where E is the energy of the incident particle and V(x) is the complex scattering potential with period Λ, which is non-vanishing in the interval 0 < x < L.The crystal length L is assumed to be an integer multiple of the lattice period Λ, i.e. L = NΛ, where N is the number of unit cells in the crystal.
