Application of Cherenkov radiation in tumor imaging and treatment.
Future Oncology, 2022Cherenkov radiation (CR) is the characteristic blue glow that is generated during radiotherapy or radioisotope decay. Its distribution and intensity naturally reflect the actual dose and field of radiotherapy and the location of radioisotope imaging ...

Tunable Optical Topological Transition of Cherenkov Radiation
International Conference on Infrared, Millimeter, and Terahertz Waves, 2022Cherenkov radiation is perhaps one of the most famous radiations based on free-electrons. Optical topological transition usually appears in specific metamaterials which possess topological optical properties.

Tunable Cherenkov radiation based on a van der Waals semiconductor α-MoO3 and graphene hybrid.
Optics Letters, 2022In this Letter, we explore the Cherenkov radiation properties of α-phase molybdenum trioxide (α-MoO3). We demonstrate that the asymmetric, forward, and reverse Cherenkov radiation can simultaneously exist by rotating the α-MoO3 slab at the same working ...

Unruh and Cherenkov Radiation from a Negative Frequency Perspective.
Physical Review Letters, 2021A ground-state atom uniformly accelerated through the Minkowski vacuum can become excited by emitting an Unruh-Minkowski photon. We show that from the perspective of an accelerated atom, the sign of the frequency of the Unruh-Minkowski photons can be ...

International Journal of Theoretical Physics, 1992
A new method is proposed for the construction of the theoretical Cherenkov spectrum. The expression representing the spectral energy distribution has the same form as the classical Frank-Tamm formula, but the square of the index of refraction is replaced by the real part of a dielectric function, which we interpret as a function characteristic of the ...

Cherenkov radiation as ghost instability
Physical Review DWe demonstrate that Cherenkov radiation can be interpreted as ghost instability of a certain type. Solutions of modified gravity theories often contain ghost instabilities.
