An electron-velocity-thresholdless terahertz (THz) Cherenkov radiation (CR) based on equivalent graphene plasmonic metamaterial (EGPMs) is proposed in this paper. A hyperbolic metamaterial (HMM) with ...

When a gamma ray from space strikes the upper atmosphere it triggers a cascade of particles that race through the tanks faster than light can traverse water, producing the familiar blue Cherenkov ...

An expanded version of the Radiation Exposure Compensation Act included in a major congressional spending bill could increase payments and coverage for victims of uranium mining and nuclear testing on ...

With the United States joining Israel in its attacks on Iran's nuclear program, here is what we know about the radiation threat, and other health risks.

Trump claimed that American forces had carried out a “highly successful” series of airstrikes on Iran’s three main nuclear facilities.

This paper describes a new design of a relativistic Cherenkov oscillator with strong modulation of the e-beam current at the input of two-sectioned slow-wave structure, as well as numerical and ...

With Israel intensifying its attacks on Iran’s nuclear program, and President Donald Trump hinting the U.S. might join the effort, here is what we know about the radiation threat, and other h… ...
