The harmonic wave propagates in the direction perpendicular to two homogeneous elastic layers situated between two homogeneous elastic materials. The pulse, in form of two periods of the sinus function, is approximated as a sum of 18 harmonic monochromatic waves of 18 different frequencies and amplitudes. The reflection coefficient for this sum is calculated. The reflection coefficient possesses several minima. One of them is about three times deeper than minimum corresponding to the single layer.
