Study on Propagation Properties of Orbital Angular Momentum Modes in Plasma Sheath Turbulence for Power-Exponent-Phase Airy Beams

The theory of random phase screen is adopted to establish the propagation model of power-exponent-phase airy (PEPA) beams in plasma sheath turbulence (PST) conditions. The propagation model can determine the changes in intensity, phase, and orbital angular momentum (OAM) mode distribution of PEPA beams under PST. Simulation results reveal that PEPA beams in multiple OAM modes at the source field can better suppress PST than the conventional vortex beams because the influence of turbulence is dispersed in different OAM modes. Moreover, compared with power-exponent-phase Laguerre–Gaussian (PEPL) beams, PEPA beams are better suited for transmission under plasma turbulence because of their self-focusing and self-healing properties. The results provide a theoretical basis for studying communication problems during PST.
