title = "Electron Beams with a Twist",
abstract = "The properties and behaviour of electron beams possessing orbital angular momentum are considered. Methods of their creation are discussed, but we concentrate mainly on the method involving binarized holographic masks. It is shown how suitable masks can be modelled using Bessel functions as well as Laguerre-Gaussian functions. The theoretical far-field diffraction patterns of these holograms are simulated using Fourier transform techniques and compared with the recently reported experimental results of electron vortex beams. The limitations of the masks and the potential of the technique for future research are pointed out and discussed.",
