  • Directional radiation by asymmetrical dielectric gratings
    Patent number: 3982810
    Abstract: There is disclosed a technique whereby a dielectric grating disposed on a in film that has a surface wave propagating thereon can concentrate the power from this wave into a beam that is either above or below the grating according to the profile of the grating. By this technique, surface waves traveling in different directions can be distinguished and the efficiency of optical beam couplers can be improved, among other applications.
