Abstract:
Low-frequency interference waves propagating in a thin elastic layer, which is in a rigid contact with an elastic half-space are considered. A new method for computation of low-frequency waves suggested by G. I. Petrashen allows us to compute the fields of these waves and to make some conclusions conserning its behavior. In particular, we can make a conclusion, that the upper thin layer essentially distortes signal sended deep into a medium. Bibl. 8 titles, ill. 26.
