Abstract:
A novel metamaterial slow-wave structure was proposed for an S-band reversed Cherenkov oscillator based on CST simulation. In view of the sub-wavelength and strong resonance characteristics of metamaterial, the slow-wave structure enjoyed both miniaturization and high coupling impedance. Taking, typically, the beam radius, voltage and current as 4.2 mm, 25 kV and 3 A, respectively, and the longitudinal focusing field as 0.2 T, the output power of the reversed Cherenkov oscillator was predicted as 20 kW with 27% electronic efficiency at 2.2 GHz operating frequency in a miniaturized configuration with a typical structure radius of only 20 mm. The proposed device with low beam voltage, miniaturized configuration and high efficiency has wide application prospects in narrowband communication, radar and accelerator.
