Abstract
The aim of the paper is to make the analytical formalism of Rokushima and Yamakita [J. Opt.
Sec. Am. 73, 901908 (1983)] treating the Fraunhofer diffraction in planar multilayered anisotropic gratings easily accessible to a broader community of students and non-specialists.
Many aspects of traditional electromagnetic optics are covered as special cases. The formalism is illustrated on a model simulating the diffraction on a ferromagnetic wire grating.
