ABSTRACT:
An array of field emission cathodes is formed by a plurality of pointed cold cathode elements arranged in rows and columns along microwave transmission means such as a waveguide or transmission line, into which low power microwave energy to be amplified is fed. Arranged opposite the cathode array in spaced relationship therewith is an anode structure. Running along the anode structure is a second microwave transmission means for receiving and coupling out the amplified input energy. Positioned between the anode and the cathode are a plurality of grid members for controlling the electron flow between the cathodes and the anode.
