On radiation due to homogeneously accelerating sources

TL;DR

This paper investigates electromagnetic radiation from uniformly accelerated sources, demonstrating non-zero radiation in the lab frame and exploring different frames and models to deepen understanding of the phenomenon.

Contribution

It provides a detailed analysis confirming radiation in the lab frame and compares different reference frames and source models for accelerated motion.

Findings

Radiation is non-zero in the lab (Minkowski) frame.

Different types of uniformly accelerated motion are analyzed.

Scalar wave models are used to gain further insights.

Abstract

The core of this work is an old and broadly discussed problem of the electromagnetic radiation in the case of the hyperbolic motion. We prove that the radiation is non-zero in the lab (Minkowski) frame. Further, we attempt to understand this subject better by using co-moving non-inertial frames of reference, investigating other types of uniformly accelerated motion and, finally, using scalar waves instead of point-like particles as sources of radiation.
