HORIZONTAL SHEAR SURFACE WAVES ON A LAMINATED COMPOSITE
It is shown that there exists a new class of surface waves with polarization parallel to the surface, like Love waves, that propagates along the free surface of a half-space consisting of a periodically layered composite with layers parallel to the free surface. A method is presented for deriving these horizontally polarized shear wave solutions from plane wave solutions obtained by applying Floquet's Theorem to an infinite periodically layered medium. The different types of surface wave dispersion relations obtained in this way are discussed and the physical significane of two critical points, the conical point and turning point, is noted.
