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.
