The hamronic waves propagating in an arbitrary direction in a layered elastic composite are studied. The layered elastic composite is composed of identical cel1s, consisting of N layers of anisotropic elastic materials, which repeat themselves in one direction. It is assumed that the bonding between layers is perfect, and the field variables satisfy the condition of quasi-periodicity at the boundary of a cell. The dispersion equation is derived.
