Propagation of a Lorentz Non-Uniformly Correlated Beam in a Turbulent Ocean
Photonics, 2023 We study the propagation characteristics (spectral intensity and degree of coherence) of a new type of Lorentz non-uniformly correlated (LNUC) beam based on the extended Huygens–Fresnel principle and the spatial power spectrum of oceanic turbulence.

Effect of oceanic turbulence with anisotropy on the propagation of multi-sinc Schell-model beams
Results in Physics, 2022 Using the extended Huygens-Fresnel principle, the expressions for the cross-spectral density function of both the circular and square multi-sinc Schell-model (MSSM) beams propagating in an anisotropic oceanic turbulent medium have been derived ...

Propagations of Sin-Gaussian Beam with Astigmatism through Oceanic Turbulence [PDF]
E3S Web of Conferences, 2021 The propagation behaviours of a sin-Gaussian beam (SiGB) with astigmatism in oceanic water is analysed. The analytical expressions for the average intensity of such a beam are derived by using the extended Huygens-Fresnel integral.

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 ...

A statistical approach to surface renewal: The virtual chamber concept
Agrosystems, Geosciences & Environment, 2021 In the stable conditions prevailing at night, concentrations of emitted gases (e.g., radon [Rn], carbon dioxide [CO2], methane [CH4], ammonia [NH3], and nitrous oxide [N2O]) build up at the surface, with intermittent interruptions due to the passage of ...
