ABSTRACT:
The treatment is directly effected on the waves propagated. Zones, for creating interruptions in propagation, are created on the useful surface of the propagation material. Several parallel tracks for propagating the elastic waves are thus delimited by these zones, the length and width of which are selected in dependance upon the required treatment.
