CROSS REFERENCE TO RELATED PATENT DOCUMENTS
The present document is somewhat related to the co-pending and commonly assigned patent application documents "DYNAMIC PLASMA STEERING METHOD FOR RADIANT ELECTROMAGNETIC ENERGY", Ser. No. 11,518,750; "TRANSMISSIVE DYNAMIC PLASMA STEERING
APPARATUS FOR RADIANT ELECTROMAGNETIC ENERGY", Ser. No. 11/518,741; and "REFLECTIVE DYNAMIC PLASMA STEERING APPARATUS FOR RADIANT ELECTROMAGNETIC ENERGY", Ser. No. 11/518,749; which are each filed of even date herewith. The contents of these related
even filing date applications are hereby incorporated by reference herein.
BACKGROUND OF THE INVENTION
The ability to steer or to controllably direct the path or the trajectory of a beam of radiant electromagnetic energy is a significantly useful tool in numerous radiant electromagnetic energy-based modern systems. Indeed, such ability to steer
the travel direction of energy beams can be argued to be as significant in their utility as . . . . More |

Radiant electromagnetic energy beam steering method achieved following
antenna conversion from electrical current and voltage characterized
signals to radiant wave characterized signals by way of the influence of
gaseous plasma of controlled plasma density and electron density on the
electromagnetic energy. Reflection and refraction mechanisms are used to
impose plasma influence on the steered electromagnetic energy. The
employed plasma properties are determined by an electrically energized
array of electrodes disposed along the plasma extent. Adaptation of the
method to widely differing wavelength parts of the electromagnetic energy
spectrum is included. A plurality of prior art patents is identified in
supplement of present disclosure of the invention.

We claim:
1. A plasma based dynamic method of pass through steering radiant electromagnetic energy, said method comprising the steps of: disposing an array of selectively sized ionizable plasma
gas concentration enhancing shapes in registration with electrode pairs of an array of electrode pairs received in a surface of an energy steering architecture; and modulating electron density in ionized portions of said ionizable plasma gas of said
plasma gas concentration enhancing shapes via electrical signals applied to selected of said energy steering architecture registered electrode pairs; said modulating including dynamically changing voltages and waveforms applied to said selected
electrode pairs and alteration of incident electromagnetic energy plasma pass through by ionized plasma electron density changes achieved through modulation energizing of said electrode pairs in said array of electrode pairs.
2. The plasma based dynamic method of pass through steering radi . . . . More |
