Abstract: The present invention provides an enhanced THz electromagnetic source structure achieving a very high aspect ratio of 500 to 1 of electron beam width to electron beam thickness of the electron beam moving in the direction across the grating structure while maintaining its cross-section. The structure comprises a magnetic circuit providing a unique low magnetic field slot placed in a steel core for the placement of an electron gun, thus allowing the electron beam to be focused without the interaction of a magnetic field while still supporting a high magnetic field in the grating region. Additionally, the structure comprises an electrostatic shield preventing potential difference between the anode voltage and the grounded steel core from affecting the focusing of the electron beam.

Abstract: Provided is a field emission device. The field emission device includes an insulated cathode substrate facing an anode substrate, a plurality of cathodes arranged on the cathode substrate and separated from each other, and an emitter formed on each of the cathodes. In order to prevent accumulation of charges on an exposed area of the cathode substrate between the cathodes due to electrons discharged from the emitter, the distance between the cathodes is equal to or smaller than a first threshold value, and the distance from the emitter to the end of the cathode is equal to or greater than a second threshold value. Accordingly, in the field emission device in which a plurality of cathodes are separated from each other on the same plane, it is possible to prevent abnormal field emission and arc generation due to accumulated charges between the cathodes, thereby performing stable operation.
