systems and methods for generating tunable electromagnetic waves using carbon nanotube-based field emitters

摘要

The systems and methods according to embodiments of the invention generate tunable electromagnetic waves using carbon nanotube-based field emitters. In one embodiment, a carbon nanotube-based irradiator includes: at least one carbon nanotube-based cathode itself including: a plurality of carbon nanotubes contiguous to a substrate; a plurality of anode regions; wherein each anodic region is configured to emit a distinctly different class of photons in a direction away from at least one cathode in response to the same electron reception; wherein each of the plurality of anode regions is operable to receive electrons emitted from at least one of said at least one carbon nanotube-based cathode; and wherein each of the at least one carbon nanotube-based cathode and plurality of anode regions are disposed within a vacuum compartment.
