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.

Reconfigurable electromagnetic plasma waveguide used as a phase shifter and a horn antenna

The present invention is drawn toward plasma electromagnetic waveguides and plasma electromagnetic coaxial waveguides that are reconfigurable, durable, stealth, and flexible. Specifically, the present invention discloses and describes a reconfigurable electromagnetic waveguide comprised of 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; and c) an energy source to form the plasma. Optionally, an energy modifying medium to reconfigure the waveguide such that electromagnetic waves of various wavelengths may be propagated directionally along the path may be used. Similarly, these waveguides may be modified into coaxial configurations.

Reconfigurable electromagnetic waveguide

An expandible antenna device comprising an expandible shell defining an interior chamber, wherein the shell is radially expandible from a central axis within the chamber; an elongated support structure disposed along the central axis and at least partially within the chamber; and an antenna element coupled to the shell such that the antenna is dimensionally stable when the shell is in an expanded position is disclosed. Additionally, an antenna element comprised of conductive elements joined by fluid filled bulbs or tubes wherein the fluid is capable of ionization is also disclosed.

Expandible antenna

The present invention is drawn toward a plasma antenna that is preferably reconfigurable, methods of generating plasma antennas, and a method of reconfiguring the radiation pattern of a plasma antenna. The plasma antenna is comprised of a) an enclosed chamber; b) a composition contained within the enclosed chamber capable of forming a plasma; c) at least three energizing points capable of forming electromagnetic contact with the composition; and d) an energy source coupled to the at three energizing points for developing at least one conductive path of plasma within the enclosed chamber. Preferably, a modifying mechanism may be utilized to reconfigure the conductive path.
