Abstract
Phase shifting plasma electromagnetic waveguides and plasma electromagnetic coaxial waveguides, as well as plasma waveguide horn antennas, each of which can be reconfigurable, durable, stealth, and flexible are disclosed. Optionally, an energy modifying medium to reconfigure the waveguide such that electromagnetic waves of various wavelengths or speeds can be propagated directionally along the path can be used. Similarly, these waveguides may be modified into coaxial configurations.
Claims40
A phase shifting plasma electromagnetic waveguide comprising:
- a) an elongated non-conductive enclosure defining a propagation path for directional electromagnetic wave propagation;
- b) a composition contained within the enclosure capable of forming a plasma, said plasma having a skin depth along a surface within the enclosure such that the electromagnetic waves penetrate the skin depth and are primarily propagated directionally along the path;
- c) an energy source to form the plasma;
- and
- d) an energy modifying medium to modify the density of the plasma such that electromagnetic waves of various speeds may be propagated directionally along the path.

A plasma electromagnetic waveguide horn antenna comprising:
- a) an elongated non-conductive enclosure defining a propagation path for directional electromagnetic wave propagation;
- b) a horn antenna structure electromagnetically coupled to the enclosure for emitting electromagnetic waves;
- c) a composition contained within the elongated enclosure capable of forming a plasma, said plasma having a skin depth along a surface within the enclosure such that the electromagnetic waves penetrate the skin depth and are primarily propagated directionally along the path in the direction of the horn antenna;
- and
- d) an energy source to form the plasma.
