Casimir electromotive force in periodic configurations

TL;DR

This paper demonstrates that nonparallel nanosized metal plates arranged periodically can generate a Casimir electromotive force (EMF), especially when strict periodicity is broken, with the EMF magnitude depending on geometric parameters.

Contribution

It reveals the conditions under which Casimir EMF can be generated in periodic structures with nonparallel plates, highlighting the role of geometric asymmetry.

Findings

EMF appears when periodicity is disturbed in nonparallel plates

EMF magnitude depends on angles and lengths of plates

Maximum EMF per unit length occurs at specific geometric parameters

Abstract

The possibility in principle of the existence of Casimir electromotive force (EMF) is shown for nonparallel nanosized metal plates arranged in the form of a periodic structure. It is found that EMF does not appear in strictly periodic structures with parallel plates. However, when the strict periodicity is disturbed in nonparallel plates, EMF is generated, and its value is equal to the number of pairs of plates in a configuration. Moreover, there are some effective parameters of the configuration (angles between plates, plate lengths and length to length ratios), at which the EMF generation per unit of the length of the periodic structure is maximal.
