Microwave Cherenkov Radiation from a Particle-in-flight to a Semi-infinite Layered Medium

TL;DR

This paper investigates microwave Cherenkov radiation emitted by a particle transitioning from vacuum into a semi-infinite layered medium, highlighting the redirection and monochromatic nature of the radiation due to the medium's periodic structure.

Contribution

It introduces the effect of periodic layered structures on the redirection and spectral properties of Cherenkov radiation from particles.

Findings

Part of the radiation is redirected backward by the layered medium.

The redirected radiation is quasi-monochromatic.

The periodic structure influences the radiation's spectral characteristics.

Abstract

Some part of the microwave Cherenkov radiation from a particle-in-flight from vacuum to semi-infinite layered medium is redirected by the periodical structure of medium in the backward direction. This part of radiation is quasi-monochromatic.
