The reflection and transmission characteristics of a grating of elastic cylinders arranged periodically in an elastic slab are examined. A simple approach synthesized from Fourier-Bessel expansions and the T-matrix method has been used for analysis of a two-dimensional problem involving SH waves only. It is observed that the nonspecular modes are generally very weak for such gratings in contrast with those for gratings made of periodic bimaterial interfaces.
