Abstract:Modern trends in beam-driven radiation sources include the interaction of Cherenkov wakefields with open-ended circular waveguides with complicated dielectric linings, with a three-layer dielectric capillary recently proposed to reduce radiation divergence being a representative example [Jiang S et al. 2020 Opt. Lett. 45 5416]. This paper presents a rigorous approach that allows for an analytical description of the electromagnetic processes that occur when the structure is excited by a single waveguide TM mode… Show more
