We study here the gain of an amplifier based on the Smith–Purcell effect. The grating is characterized by a reflection matrix and the gain, in the exponential region, is calculated as a function of the beam height and thickness.

    We propose a room-temperature semiconductor source of coherent narrowband Smith-Purcell radiation (SPR) in the low-to-mid terahertz range. The device is a planar Gunn diode with a metallic grating deposited near the drift region. Stimulated SPR is generated as domains move under the grating....

    The Cherenkov radiation and/or Smith-Purcell radiation, which are generated by electrons that move compactly along the surface of a slow-wave structure, can be modulated by deflecting of electron beam. When a resonant optical beam is incident, the structure functions as an amplifier. Swinging...

    The design of free-electron lasers (FELs) based on submillimeter-range undulators involves difficulties associated with the fabrication of undulators with a very small period. To do this also requires accelerators with high-energy electron beams (>50 MeV). It should also be taken into account...

    Grazing-angle scattering (GAS) is a type of Bragg scattering in slanted wide periodic gratings. It occurs when the diffracted order satisfying the Bragg condition (scattered wave) propagates at a grazing angle to the grating boundaries. Previous research has been concerned only with first-order...

    The orotron is a device in which a sheet electron beam excites electromagnetic (EM) oscillations in an open resonator formed by a concave mirror and a periodic grating plate. The first spatial harmonic of a field near the grating has phase velocity close to electron velocity; therefore electrons...

    A model is proposed for calculating the angular distributions of the intensity of resonant diffraction radiation generated by a charged particle moving near a plane conducting periodic structure (Smith-Purcell radiation) with allowance for the effect of the so-called pre-wave zone. It is shown...
