Orbital angular momentum (OAM) of waves is a property associated with the spatial distribution of phase and amplitude in a wave field. It is particularly important in the context of electromagnetic waves, matter waves (like electrons), and other wave phenomena. OAM arises in systems where the wavefronts can take on complex shapes, resulting in a twist or helical structure.
