Vavilov-Cherenkov like mechanism of surface wave excitation_details of calculations

TL;DR

This paper details calculations showing that fast-moving charged particles can excite surface waves in thin metal films at velocities much lower than those needed in uniform media, revealing a Vavilov-Cherenkov-like effect.

Contribution

It provides a detailed theoretical analysis of surface wave excitation by charged particles in thin metal films, extending the understanding of Vavilov-Cherenkov-like phenomena to lower particle velocities.

Findings

Surface waves can be excited at significantly lower particle velocities.

The effect is analogous to Vavilov-Cherenkov radiation but occurs in thin metal films.

Theoretical calculations support the possibility of observing this effect.

Abstract

This paper contains details of calculation of the surface wave excitation by a fast moving charged particle in a thin uniform metal film surrounded by a dielectic medium. Early on the effect was described in the paper arXiv:0911.0565 03 November 2009. It is shown that the Vavilov-Cherenkov like effect for the surface waves could arise for particles whose velocities are ten- and even hundred-times lower than the corresponding velocities in a uniform medium.
