Orbital angular momentum (OAM) is a property of electromagnetic waves that refers to the rotation of the wavefront in a spiral pattern around its propagation axis. This property arises due to the spatial distribution of the wave's phase, which gives rise to a helical phase front. OAM has been studied extensively in the field of optics and photonics, where it has been shown to have applications in optical communications, imaging, and microscopy. In recent years, researchers have also been exploring the use of OAM in other areas such as quantum information processing and radio frequency communications. This research area has the potential to open up new opportunities for manipulating and controlling light and other forms of electromagnetic radiation.
