Nonparaxial effects in lensacon optical systems

Аннотация

This paper presents a brief overview of papers dealing with the nonparaxial effects arising from the use of the lensacon proposed by Koronkevich and coauthors in 1993, as well as its analogs in a substantially nonparaxial mode. In this case, it is necessary to take into account the vector nature of electromagnetic radiation. This allows detecting new effects, which, in turn, would extend the range of applications of the lensacon.
