Propagation of a polychromatic stochastic electromagnetic multi-Gaussian Schell-model vortex beam in oceanic turbulence

Abstract

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.
