Effect of oceanic turbulence on the statistical features of electromagnetic optical beam

Results in Physics
This work deals with the intricate problem of electromagnetic optical beam propagation through oceanic turbulence. Using the extended Huygens–Fresnel principle, numerically, the behavior of the degree of cross-polarization (DOCP), electromagnetic degree ...

Impact of Beacon Feedback on Stabilizing RL-Based Power Optimization in SLM-Controlled FSO Uplinks Under Turbulence

Photonics
Atmospheric turbulence severely limits the stability and reliability of free-space optical (FSO) uplinks by inducing wavefront distortions and random intensity fluctuations. This study investigates the use of reinforcement learning (RL) with beacon-based
