One of the possible ways of formulation of an information loss paradox refers to an entanglement of the two particles created in a vicinity of an event horizon. Evolution of the entangled particles and an interaction with their own environments should lead to a decay of the entanglement. However obvious, such a perspective appears to be too naive in this case.

The behavior of the structure amplitude is analyzed in terms of the harmonics of a modulation function for the case of one-dimensional longitudinal displacive modulation. This modulation function is given by a finite series of N sine functions. It turns out that: (1) for the large values of the amplitudes of the modulation function the structure amplitude tends to zero for the arbitrary values of the order m of the satellite reflections; (2) for certain values of the amplitudes of the modulation function the modulus of the structure amplitude assumes its maximum value and (3) for the latter case the intensity of an arbitrary satellite reflection is a function of the intensities of both the closest main reflection and the intensities of the finite set of the neighbor satellite reflections.
