The diffraction of electromagnetic waves at the surface periodic structures
accompanied by strong anomalous effects in different diffraction orders is
considered in great detail for high-contrast interfaces. We restrict our
discussion to the TM polarization of the incident wave (the magnetic field is
orthogonal to the plane of incidence) and the simplest geometry when the plane
of incidence is orthogonal to the grating grooves. The most attention is
focused on the strong maxima and minima of the energy flux density accompanying
specific grazing propagation of some diffraction order. Relation to other
anomalies, both Rayleigh and the resonance ones is discussed as well.
