title: X-ray gratings: the GMS mount.
abstract: Using rigorous electromagnetic theory, the interest of the specific off-plane mounting for x-ray gratings is discussed in detail. The optimization of the blaze angle for ruled gratings is considered, as well as the extension of the mounting to sinusoidal and lamellar profiles.
