Abstract
Reflection of light from a high spatial frequency lamellar grating at a glass-air (Θ>Θc) or glass-metal interface introduces a phase shift between the orthogonal polarization components. If a conventional incidence geometry is used (grating vector parallel to the plane of incidence), no polarization conversion occurs. Thus, gratings of this type can be used as phase compensation and retardation elements operating on a specularly reflected beam.
