Smith–Purcell radiation of a vortex electron
A wide variety of emission processes by electron wave packets with an orbital angular momentum ℓℏ , called the vortex electrons, can be influenced by a nonparaxial contribution due to their intrinsic electric quadrupole moment. We study Smith–Purcell radiation from a conducting grating generated by...
