Abstract
An emitter, a field emission assembly, and an electromagnetic wave generator are provided, and the emitter is an emitter for emitting electrons in an electromagnetic wave generator and is in the form of a sheet in which a plurality of yarns including carbon nanotube (CNT) fibers are weaved.
Claims20
A field emission assembly, comprising
- an emitter configured to emit electrons;
- and
- a holder configured to fix the emitter,
- wherein the emitter is in the form of a sheet in which a plurality of yarns including carbon nanotube (CNT) fibers are weaved,
- wherein the emitter includes an electron emission portion which is a region spread on a plane perpendicular to the electron emission direction, and side portions formed on both sides of the electron emission portion,
- wherein the holder includes a seating part on which the emitter is seated, and fixing parts disposed on both sides of the seating part,
- wherein the electron emission portion is seated on a front surface of the seating part in the electron emission direction, and
- wherein the side portions are disposed in gaps formed between the seating part and the fixing parts while surrounding the seating part.
