A model for electromagnetic multi-Gaussian Schell-model beams is introduced. An analyticalexpression for the cross-spectral density matrix of electromagnetic multi-Gausssian Schell-model(EMGSM) beams propagating through non-Kolmogorov turbulence is derived based on the extendedHuygens-Fresnel principle. With help of this expression, the average intensity, degree of coherence(DOC) and degree of polarization (DOP) of EMGSM beams are investigated in detail. Our resultsshow that by suitable choices of the source parameters, the distance that preserve a flat profile canbe prolonged. The effects of M and exponent value on DOC and DOP of EMGSM beams arestudied in detail.
