Abstract

We analyze and describe the evolution of the Poynting vector and angular momentum of the Airy beam as it propagates through space. A numerical approach is used to show the Poynting vector follows the tangent line of the direction of propagation. A similar approach is used to show that while the total angular momentum of the Airy beam is zero, the angular momentum of the main intensity peak and the Airy tail are non-zero. These beams have promise for applications in imaging and spectroscopy where a sample might interact with a changing momentum and spatially varying angular momentum.
