Research Progress in Reversed Cherenkov Radiation in Double-negative Metamaterials
We review the research progress in reversed Cherenkov radiation in double-negative metamaterials (DNMs) starting from the first experimental verification of the DNMs reported in 2001, including theories, numerical computation and simulation and experiments. We also discuss the potential applications to particle detectors and highpower microwave or millimeter-wave devices, including the oscillat...
متن کاملFlipping Photons Backward: Reversed Cherenkov Radiation Inspired by Metamaterials
Charged particles traveling through a conventional medium at a speed greater than the speed of light in the medium produce Cherenkov radiation in the forward directions, which is useful for particle identification and counting. Newly designed metamaterial, with their negative index of refraction, flips the radiated photons backward and thus readily separates the radiation from the emitting part...
متن کاملControlling Cherenkov radiation with transformation-optical metamaterials.
In high energy physics, unknown particles are identified by determining their mass from the Cherenkov radiation cone that is emitted as they pass through the detector apparatus. However, at higher particle momentum, the angle of the Cherenkov cone saturates to a value independent of the mass of the generating particle, making it difficult to effectively distinguish between different particles. ...
متن کاملDesign of Dual-Band Double Negative Metamaterials
A dual-band artificial magnetic material and then a dual-band double-negative metamaterial structure based on symmetric spiral resonators are presented. An approximate analytical model is used for the initial design of the proposed structures. The electromagnetic parameters of the proposed metamaterial structure retrieved using an advanced parameter retrieval method based on the causality princ...
متن کاملObservation of the reversed Cherenkov radiation
Reversed Cherenkov radiation is the exotic electromagnetic radiation that is emitted in the opposite direction of moving charged particles in a left-handed material. Reversed Cherenkov radiation has not previously been observed, mainly due to the absence of both suitable all-metal left-handed materials for beam transport and suitable couplers for extracting the reversed Cherenkov radiation sign...
