Three wave interaction analysis in the presence of far-reaching correlations of stochastic irregularities

The propagation of wave triplet is investigated in media which is composed of large periodically repeating stochastic pieces. The correlation scale of the nonuniformities is assumed to be small within one period (delta correlation), but there is strong correlation of irregularities at the distance equal to the media period. We have examined the waves properties verses to the multiple of pass of the identical piece. The results obtained demonstrate the substantial dependence of the solutions from the existence of random parameter far-reaching correlations
