Abstract
The results of numerical analysis of the acoustic field excited in an elastic layer and in ambient media by an oscillating infinitely extensive point dipole source with the moment oriented parallel to the laminar structure layers are given. Spatial distribution of the amplitude of the SH-wave field, propagating in the direction perpendicular to the moment, in the layer and beyond it is analyzed. The problem is solved in a two-dimensional statement at different ratios of parameters of elastic rigidity of the inner and outer regions of the laminar structure at different vibrational frequencies.
