Abstract
A device couples energy from an electromagnetic wave to charged particles in a beam. The device includes a micro-resonant structure and a cathode for providing electrons along a path. The micro-resonant structure, on receiving the electromagnetic wave, generates a varying field in a space including a portion of the path. Electrons are deflected or angularly modulated to a second path.

- 49. A signal modulator that alters a detectable characteristic of a charged particle beam passing by but not touching a microscopic structure, the microscopic structure having a physical dimension causing the microscopic structure to develop an electric field that alters the detectable characteristic of the charged particle beam when the microscopic structure is contacted by electromagnetic radiation of one or more predetermined frequencies greater than microwave frequency.

62. A system for detecting the presence of electromagnetic radiation using charged particles moving along a path, comprising:
an ultra-small resonant structure that, when induced by the presence of the electromagnetic radiation, produces resonance at frequencies in excess of microwave frequencies, said resonance inducing a varying force on the charged particles to thereby cause the charged particles to detectably alter from their movement along the path. - View Dependent Claims (63, 64, 65, 66)

67. A method of coupling energy from an electromagnetic wave to a charged particle beam, comprising the steps of:
-
receiving an electromagnetic wave at an ultra-small resonant structure constructed and adapted to generate a varying field on receiving the electromagnetic wave;
approaching a charged particle beam to the varying field to cause the charged particle beam to be angularly modulated by the varying field. - View Dependent Claims (68)
