DOI: 10.1080/09500340.2019.1674393
Abstract: ABSTRACT The fundamental problem of propagation invariant Bessel beams is that they are not square-integrable in the transverse direction, and are therefore associated with an infinite power flux. Hence, truncated Bessel beams are typically considered… read more here.
