PHASED ELECTROMAGNETIC MATRIX RADIATION SOURCE Russian patent published in 2006 - IPC H01J25/55 

FIELD: electromagnetic radiation sources including phased matrix ones.

SUBSTANCE: proposed electromagnetic radiation source has anode and cathode separated by anode and cathode space as well as electric contacts for applying DC voltage between anode and cathode. At least one magnet is used to build DC magnetic field in cathode-anode space actually perpendicular to electric field. There are many waveguides within anode which have anode-cathode space holes formed along anode surface and used to locate anode-cathode space with the result that cathode-emitted electrons actuated by electric and magnetic fields follow path in anode-cathode space in immediate proximity of holes. Common resonator receives electromagnetic radiation induced in holes due to passage of electrons in immediate proximity of holes and reflects electromagnetic radiation back to holes to create oscillating electric fields in each of holes at desired operating frequency.

EFFECT: improved design.
