Propagation Factor And Beam Wander Of Electromagnetic Gaussian Schell-Model Array Beams In Non-Kolmogorov Turbulence

The propagation formulae for the propagation factor (known as M-2-factor) and beam wander of electromagnetic Gaussian Schell-model (EGSM) array beams in non-Kolmogorov turbulence are derived by using the extended Huygens-Fresnel principle and the second-order moments of the Wigner distribution function. The results indicate that the M-2-factor and beam wander depend on the beam parameters and turbulence parameters, and the relative M-2-factor has a maximum when the generalized exponent parameter a is equal to 3.1. Otherwise, the changes of the separation distances (x(0), y(0)) have great influence on the relative M-2-factor. The relative beam wander increases rapidly when 3更多
