Abstract

The configurations of rays passing through the axicon are considered, which take into account the presence of both reflected and refracted rays at the boundary of the media. This is important for such values of the angle at the apex of the axicon, when the Fresnel coefficient for the reflected beam is greater than for the refracted one. The passage of rays through the semi-axicon is also considered. An example of quantitative calculation is given, showing that this effect allows forming two divergent conical beams having comparable amplitude at once.
