4x4 ray matrix for a curved chirped grating at oblique incidence.
The general 4x4 ray matrix of a grating is presented. This matrix suits the cases of transmission and reflection by a chirped grating with curved lines lying on a curved interface. The matrix presented applies to the general oblique incidence of the optical axis and therefore to nonorthogonal cases and to conical diffraction.
