Abstract

This work is devoted to a theoretical study of diffracted light by an hemispherical track. Within the framework of the Fraunhofer diffraction theory, we investigate the intensity characteristics in the far-field region for a diffractive hemispherical aperture illuminated by a plane wave. Some practical numerical examples are also illustrated.

Keywords : Hemispherical aperture; Fraunhofer diffraction; Far-field region.
