Flipping 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 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...
متن کاملCoherent Cherenkov-Cyclotron Radiation Excited by an Electron Beam in a Metamaterial Waveguide.
An electron beam passing through a metamaterial structure is predicted to generate reversed Cherenkov radiation, an unusual and potentially very useful property. We present an experimental test of this phenomenon using an intense electron beam passing through a metamaterial loaded waveguide. Power levels of up to 5 MW are observed in backward wave modes at a frequency of 2.40 GHz using a one mi...
متن کاملReal-time in vivo Cherenkoscopy imaging during external beam radiation therapy.
Cherenkov radiation is induced when charged particles travel through dielectric media (such as biological tissue) faster than the speed of light through that medium. Detection of this radiation or excited luminescence during megavoltage external beam radiotherapy (EBRT) can allow emergence of a new approach to superficial dose estimation, functional imaging, and quality assurance for radiation ...
