Bessel beams, propagationally invariant beams, and axicons: An historical and tutorial review
arXiv:2509.06354
Abstract
The Bessel beam is discussed, including its historical development. We present the relationship with the Arago Spot, annular pupils, axicons and pupil filters. We also discuss Bessel-Gauss beams; higher order Bessel beams; electromagnetic polarization properties; waveguide and resonator modes; polychromatic and pulsed beams; one-dimensional Airy beams; extended depth of focus; and light sheets and photonic nanojets.
