Abstract :
The existence is demonstrated of a new type of acoustic surface wave that has a horizontally polarised shear displacement and which propagates along the free surface of a halfspace comprised of a periodically layered composite. This wave contrary to other types of dispersive waves, has unique bandpass and bandstop dispersive characteristics that suggest new filter applications.
