| Abstract: | A diffractive slab structure comprising a mirror, a dielectric film, and a grating in the film is made to always exhibit 100% diffraction efficiency for the – 1st order pointing in a backward direction. The design is obtained by sole interference reasoning, and confirmed numerically. |
