Geometrical optics and the diffraction phenomenon


National Research Centre Kurchatov Institute, pl. akad. Kurchatova 1, Moscow, 123182, Russian Federation

This note outlines the principles of the geometrical optics of inhomogeneous waves whose description necessitates the use of complex values of the wave vector. Generalizing geometrical optics to inhomogeneous waves permits including in its scope the analysis of the diffraction phenomenon.
