Explicit derivation of the Fraunhofer diffraction formula for oblique incidence
arXiv:2104.08073 · doi:10.1088/1361-6404/ac2ece
Abstract
We have analytically explored the Rayleigh-Sommerfeld scalar diffraction for oblique incidence. We have explicitly derived the Fraunhofer diffraction formulae for oblique incidence of plane scalar wave on various apertures, such as single-slit, circular aperture, and diffraction grating. Such derivations in the background of Rayleigh-Sommerfeld scalar diffraction theory would be important for an undergraduate course on optics.
