Research Progress in Reversed Cherenkov Radiation in Double-Negative Metamaterials
TL;DR: Duan et al. as mentioned in this paper reviewed the research progress in reversed Cherenkov radiation in double-negative metamaterials starting from the first experimental verification of the DNMs reported in 2001, including theories, numerical computation and simulation and experiments.
Journal ArticleDOI
Sine Waveguide for 0.22-THz Traveling-Wave Tube
TL;DR: In this paper, a novel slow-wave structure called sine waveguide has been proposed to develop a wideband high-power terahertz radiation source, which evolves from a rectangular waveguide oscillating with sinusoid along its longitudinal direction.

TL;DR: An all-metal metamaterial, consisting of a square waveguide loaded with complementary electric split ring resonators, is developed and demonstrated that it exhibits a left-handed behaviour, and directly observe the Cherenkov radiation emitted predominantly near the opposite direction to the movement of a single sheet electron beam bunch.
Journal ArticleDOI
W-Band 1-kW Staggered Double-Vane Traveling-Wave Tube
TL;DR: In this article, a W-band traveling-wave tube (TWT) with a staggered double-vane slow-wave structure combined with a sheet electron beam was designed to achieve an output power of over 1 kW.
Journal Article
Observation of the reversed Cherenkov radiation
TL;DR: In this article, an all-metal metamaterial, consisting of a square waveguide loaded with complementary electric split ring resonators, has been developed for left-handed Cherenkov radiation.
