Abstract
An electromagnetic energy collector and sensor use enhanced fields to emit electrons for energy collection. The collector and sensor collect energy from visible light, infrared radiation and ultraviolet electromagnetic radiation. The collector and sensor include a waveguide with a geometry selected to enhance the electric field along a conductor to create a high, localized electric field, which causes electron emission across a gap to a return plane.

11. A method for collecting electromagnetic energy and generating electrical energy, the method comprising:
-
receiving the electromagnetic energy into a first end of at least one collection structure having a first cross-sectional dimension defined by an inner surface of the at least one collection structure; propagating the electromagnetic energy toward a second end of the at least one collection structure, the second end of the at least one collection structure having a second cross-sectional dimension smaller than the first cross-sectional dimension, the cross-sectional dimension of the at least one collection structure varying between first dimension and the second dimension and having at least one dimension between the first dimension and the second dimension corresponding to a wavelength of the electromagnetic energy; and interacting the electromagnetic energy with the inner surface of the at least one collection structure where the wavelength of the electromagnetic energy corresponds to the at least one dimension of the at least one collection structure to create an emission of electrons from the at least one collection structure to an anode because of the interaction of. - View Dependent Claims (12, 13)
