| http://www.w3.org/ns/prov#value | - Bragg resonant tuning results when the parameters such as wavelength and incident angle are varied in a coupled fashion so that the grating and Bragg equations are simultaneously satified The Bragg-resonant conditions for the more general case of a volume transmission grating where the scattering center- or refractive index-distributions are tilted by an angle ?? with respect to those shown in F
