  text: The Smith-Purcell effect, observed when an electron beam passes in the vicinity
    of a periodic structure, is a promising platform for the generation of electromagnetic
    radiation in previously unreachable spectral ranges. However, most of the studies
    of this radiation were performed on simple periodic gratings, whose radiation
    spectrum exhibits a single peak and its higher harmonics predicted by a well-established
    dispersion relation. Here, we propose a method to shape the spatial and spectral
    far-field distribution of the radiation using complex periodic and aperiodic gratings.
    We show, theoretically and experimentally, that engineering multiple peak spectra
    with controlled widths located at desired wavelengths is achievable using Smith-Purcell
    radiation. Our method opens the way to free-electron-driven sources with tailored
    angular and spectral responses, and gives rise to focusing functionality for spectral
    ranges where lenses are unavailable or inefficient.
