The analytical equations of the polychromatic stochastic electromagnetic multi-Gaussian Schell-model vortex (EMGSMV) beam through oceanic turbulence are obtained in theory. The influences of source parameters and turbulence on changes in spectral shifts and polarization of a polychromatic EMGSMV beam are numerically analyzed. It is seen that the relative spectral shift of such beam with larger N , smaller l and smaller δ0 will evolve from red shift to blue shift on propagation, and the polarization can become poor when a polychromatic EMGSMV beam propagates in stronger oceanic turbulence.
Based on the extended Huygens-Fresnel principle, the propagation equations of rectangular multi-Gaussian Schell-model (MGSM) beam array generated by the multi-Gaussian Schell-model source in maritime atmospheric turbulence are derived. The evolutions and effective beam widths of MGSM beam array propagating in maritime atmospheric turbulence are analyzed by using numerical examples. The obtained results are beneficial to the practical application of MGSM beam array in maritime atmosphere.
