1. A device for coupling energy from an electromagnetic wave to a charged particle beam, the device comprising:
- an ultra-small micro-resonant structure having a surface for receiving the electromagnetic wave, said ultra-small micro-resonant structure constructed and adapted to generate a varying field on receiving the electromagnetic wave, and to cause a charged particle beam approaching the varying field to be modulated; and
a source providing the charged particle beam, wherein the charged particle beam comprises particles selected from the group comprising;
electrons, positive ions, negative ions, and protons, said particle beam being provided along a generally-straight first path toward the varying field,wherein the micro-resonant structure includes a region with varying field, wherein the charged particle beam exits the region along a generally-straight second path distinct from the first path, wherein an angle between the first path and the second path is related, at least in part, to a magnitude of the energy coupled from the electromagnetic wave to the charge particle beam.

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.
