Sustained, Localized, Pulsed-Microwave Discharge in Air

Abstract

SEVERAL recent publications1–4 discuss possible methods whereby a localized gas discharge might be maintained by electromagnetic radiation. Recently a simple experiment to maintain an electrodeless discharge by focused microwave radiation was undertaken at this Laboratory. A small, localized discharge was obtained in low-pressure air. This discharge stands distinct and isolated from the generating apparatus and from any walls.
