# Casimir EMF in configurations with shifted elements

## TL;DR

This paper demonstrates theoretically that a Casimir electromotive force can be generated in nanoscale metal plate configurations when the plates are shifted relative to each other, with potential for maximal EMF at specific geometrical parameters.

## Contribution

It introduces the novel concept that shifting parallel nanosized metal plates can produce a Casimir EMF, expanding understanding of Casimir effects in shifted configurations.

## Key findings

- EMF appears only when plates are shifted, not when perfectly parallel.
- Maximal EMF depends on the degree of shift and configuration angles.
- Periodic shifted configurations can generate sustained EMF with optimal geometries.

## Abstract

The possibility in principle is shown for the existence of Casimir electromotive force (EMF) in a configuration with parallel nanosized metal plates which are shifted relative one another. The effect is theoretically demonstrated for a configuration with two plates (wings) of finite length, the particular case of which is classical Casimir configuration with parallel plates. It is found that when the plates are strictly parallel, EMF does not appear. However, when the plates are shifted relative one another, in each of them time-constant EMF is generated. It is also found that maximal EMF values depending on the plate shifts are larger than those depending on the values of angles between the wings. All the found effects exist in periodic configurations with shifted elements. There are optima of the configuration geometrical parameters at which the EMF generation can be maximal.
