Spin and Orbital Angular Momenta of Electromagnetic Waves: From Classical to Quantum Forms
arXiv:2403.01504 · doi:10.1109/JMMCT.2024.3370729
Abstract
Angular momenta of electromagnetic waves are important both in concepts and applications. In this work, we systematically discuss two types of angular momenta, i.e., spin angular momentum and orbital angular momentum in various cases, e.g., with source and without source, in classical and quantum forms. Numerical results demonstrating how to extract the topological charge of a classical vortex beam by spectral method are also presented.
