Abstract
The transfer matrix of a layer is derived from the dynamic equations o f a continuum reinforced with very thin unstretchable membranes. For t he case of a periodically spaced reinforcement, the finite difference method enables to find closed solutions. The elastic wave propagation in a half-space is investigated, and it is shown that the only possibl e nonattenuating wave has the velocity c(2) of the shear wave.
