A fully vectorial treatment of the problem of scattering by singly periodic interfaces between chiral and achiral media has been presented. By means of an improved T-matrix method of solution, this treatment is able to bypass the restrictions imposed by the Rayleigh hypothesis. In addition, solutions to several other related problems can be obtained by the method presented here. The specific features of the solution procedure allow it to be converted easily for doubly periodic interfaces. The analysis may be useful for developing new surface-relief gratings made using chiral materials.
