The Classical and Generalized Love Problems in a Domain of Low-Frequency Interference Waves of Signal Type. II

Computations of low-frequency interference waves of SH type are performed for the generalized Love problem. The model of a medium consists of a thin elastic layer, a thick layer, and a half-space. The layers and half-space are in rigid contact with each other. It is assumed that the waves pass through the thick layer twice, there and back. A new method, suggested by G. I. Petrashen, for computing wave fields allows us to compute the fields of SH waves and to draw conclusions concerning their behavior. The computations are carried out for < 1 and > 1, where is the ratio of the velocities in the thin and thick layers. In either case, the thin layer significantly distorts a signal transmitted deep into the medium. Bibliography: 6 titles.
