Similarly to electromagnetic waves, plasma waves can also carry an orbital angular momentum. A key distinction from electromagnetic waves is that plasma waves are intrinsically coupled to electrons and may deposit their momentum with electrons, resulting in their secular motion and generation of quasistatic magnetic fields. In this paper, we present an analysis of kinetic plasma waves carrying an orbital angular momentum in the paraxial approximation by considering the energy and momentum exchange between the wave and electrons and the average electron motion induced by plasma wave damping.
