Poynting vector for Cauchy-Riemann beams

Optics 2024-10-21 v1

Abstract

We present a detailed derivation of the Poynting vector for Cauchy-Riemann beams propagating in free space considering a Gaussian modulation with gCg \in \mathbb{C}. The effect generated by this Gaussian modulation is a compression-expansion of the intensity distribution. It is shown that the parameter gg can reverse the direction of energy flux and eliminate the radial component, resulting in a purely azimuthal field. Additionally, we validate our analytical results through experimental verification.
