Microwave Radiation from a Particle Revolving Along a Shifted Equatorial Orbit About a Dielectric Ball

TL;DR

This paper investigates how a relativistic electron orbiting a dielectric ball can produce significantly amplified microwave Cherenkov radiation compared to an infinite medium, highlighting potential for enhanced radiation sources.

Contribution

It introduces the concept that a shifted equatorial orbit around a dielectric sphere can substantially increase microwave Cherenkov radiation intensity.

Findings

Microwave radiation intensity can be tens of times higher than in infinite media.

Relativistic electrons on shifted orbits produce enhanced Cherenkov radiation.

The geometry of the orbit significantly influences radiation strength.

Abstract

A relativistic electron uniformly rotating along a shifted equatorial orbit about a dielectric ball may generate microwave Cherenkov radiation tens of times more intense as that generated at the revolution in a continuous, infinite and transparent medium.
