✦ Synopsis

The approach suggested in [l, 21 is applied to the problem of the propagation of a plan longitudinal wave in an elastic medium containing a periodic system of rectangular defects. Explicit analytical representations for the scattering coefficients as well as a refined low-frequency solution are derived using a uniform approximation of the single-mode type. A comparison of the results with solutions obtained by other methods is given.
