Percolation transition in the kinematics of nonlinear resonance broadening in Charney–Hasegawa–Mima model of Rossby wave turbulence [PDF]
, 2013 We study the kinematics of nonlinear resonance broadening of interacting Rossby waves as modelled by the Charney-Hasegawa-Mima equation on a biperiodic domain. We focus on the set of wave modes which can interact quasi-resonantly at a particular level of

Bit error rate performance of underwater optical wireless communication with hybrid modulation
IET Communications, 2023 Turbulence effects can cause performance degradation for underwater optical wireless communication (UOWC) system. In this paper, a hybrid modulation (modulation–modulation, M–M) is presented to resist turbulence‐induced fading and improve the ...

Effects of Oceanic Turbulence on Orbital Angular Momenta of Optical Communications
Journal of Marine Science and Engineering, 2020 The propagation properties of Laguerre-Gaussian beams in oceanic turbulence are investigated for both single-photon and biphoton cases. For single-photon communication, the channel capacity and trace distance are employed, both of which effectively ...

Propagation Factors of Partially Coherent Model Beams in Oceanic Turbulence
IEEE Photonics Journal, 2017 Based on the extended Huygens–Fresnel principle and second-order moments of the Wigner distribution function, we have derived the analytical expressions of the propagation factor of four kinds of partially coherent model beams in oceanic ...
