Digital Subtractive Angiography (DSA) has been performed to image human coronary arteries using wiggler radiation from electron storage rings. The significant medical promise of this procedure motivates the development of smaller and less costly x-ray sources. Several exotic sources are candidates for consideration, using effects such as Cherenkov, channeling, coherent bremsstrahlung, laser bac...
Relativistic plasma masers operating on the anomalous cyclotronCherenkov resonance ω − k‖v‖ + ωB/ γres = 0 and the Cherenkov-drift resonance ω − k‖v‖ − kxud = 0, are capable of explaining the main observational characteristics of pulsar radio emission. Both electromagnetic instabilities are due to the interaction of the fast particles from the primary beam and from the tail of the secondary pai...
Abstract Chasing efficient methods to generate and manipulate Cherenkov radiation (CR) is always the lofty target of many scientific researchers. In this work, by combining optical topological transition (OTT) graphene hyperbolic metamaterials (GHMs), we study properties clarify mechanisms OTT CR for first time. Specifically, indicate two representative examples reveal potential in manipulating...
By using a phased electromagnetic dipole array to model a moving charged particle, we experimentally verified a reversed Cherenkov radiation in the left-handed media in the frequency range from 8.1 to 9.5 GHz. Our results demonstrate the feasibility of new types of particle detectors and radiation generators.
