Motion-induced radiation in a cavity with conducting and permeable plates

Abstract

We consider a conducting and a permeable plate immersed in the vacuum of a scalar field. We calculate the photon production rate when two plates at a distance $H$ oscillate with a frequency ${\ensuremath{\omega}}_{p}$. For $H{\ensuremath{\omega}}_{p}∕(\ensuremath{\pi}c)<2$, the angular spectrum and photon production rates are significantly different from those of a conventional cavity with two conducting or two permeable plates.
