		Plasma stealth is a proposed process that uses ionized gas to reduce the radar cross section (RCS) of an aircraft.
		The use of plasmas to control the reflected electromagnetic radiation from an object (Plasma stealth) is feasible at higher frequency where the conductivity of the plasma allows it to interact strongly with the incoming radio wave, but the wave can be absorbed and converted into thermal energy rather than reflected.
		Control of plasma properties is likely to be important for a functioning plasma stealth device, and it may be necessary to dynamically adjust the plasma density, temperature or composition, or the magnetic field, in order to effectively defeat different types of radar systems.

		Increased awareness of stealth vehicles and the technologies behind them is prompting the development of techniques for detecting stealth vehicles, such as passive radar arrays and low-frequency radars.
		As well as altering the tail, stealth design must bury the engines within the wing or fuselage, or in some cases where stealth is applied to an existing aircraft, install baffles in the air intakes, so that the turbine blades are not visible to radar.
		To achieve infrared stealth, the exhaust gas is cooled to the temperatures where the brightest wavelengths it radiates on are absorbed by atmospheric carbon dioxide and water vapor, dramatically reducing the infrared visibility of the exhaust plume.

		Different types of plasma are as far from each other in their physical properties as the fluorescent light in your kitchen is different from the solar core or as Aurora Borealis is different from magnetic confinement fusion.
		Plasma is a quasineutral (total electrical charge is zero) mix of various particles and should not be confused with full ionization.
		Plasma exists at normal atmospheric pressure and serves as an electrohydrodynamic coupling layer between the artificially-generated (by the aircraft's onboard systems) electric field and the electrically neutral boundary layer.

		Plasma cloud is a quasineutral (total electrical charge is zero) collection of free charged particles.
		Plasma physics was given priority in Russia many years ago, which resulted in a number of breakthroughs in theory as well as practical applications of plasma.
		Plasma is ionized gas, which means that it's atoms have so much kinetic energy that valence electrons have been freed through atomic-level collisions.

	Markland Technologies: Gas Plasma
		Plasmas have a much wider range of power capability than metals as evident from low powered plasma in fluorescent bulbs to extremely high-powered plasmas in the Princeton University experimental fusion reactors.
		The theoretical calculations on the controlled variation of plasma density in space and time suggest that greater bandwidth of the plasma antenna can be achieved than the corresponding metal antenna of the same geometry.
		One option is to construct controlled density plasma blankets around plasma antennas thereby creating windows (low-density sections of the blanket) for main lobe transmission or reception and closing windows (high-density regions in the plasma blanket).

		The Russians seemed to be years ahead, even marketing a plasma stealth add-on device said to reduce radar returns by a factor of a hundred.
		Note also the wording in Patent 3,713,157 which says that the plasma cloud produces a combination of ‘absorbtion, reflection, refraction and diffraction’ across frequencies including visible spectrum, which would certainly alter the appearance of an aircraft, perhaps to the point of making it an unrecognisable blob.
		Given that the radioactive plasma coating was known to improve aerodynamics and stealthiness in the 1960’s, we would expect the next step to be a way of achieving the same benefits without radioactivity.

	Stealth Technology - History of stealth technology, Stealthy flying, █ further reading:
		Stealth technology, also termed "low-observable" technology, is a set of techniques that render military vehicles, mostly aircraft, hard to observe.
		Development of stealth technology for aircraft began before World War I. Because RADAR had not been invented, visibility was the sole concern, and the goal was to create aircraft that were hard to see.
		Plasma absorbs radio waves, so it is theoretically possible to diminish the RADAR reflectivity of an otherwise non-stealthy aircraft by a factor of 100 or more by generating plasma at the nose and leading edges of an aircraft and allowing it flow backward over the fuselage and wings.

	.::What is Stealth Technology?::.
		Stealth or low observability (as it is scientifically known) is one of the most misunderstood and misinterpreted concepts in military aviation by the common man. Stealth aircraft are considered as invisible aircraft, which dominate the skies.
		The motive behind incorporating stealth technology in an aircraft is not just to avoid missiles being fired at is but also to give total deniability to covert operations.
		Plasma stealth technology is what can be called as "Active stealth technology" in scientific terms.

	Aerospace Industry Discussion
		Even if active stealth produces a better reduction of RCS than passive stealth, it creates new ways of being detected, which are necessary for the anit-radar plasma stealth to work.
		The active stealth may be cheaper, but the aerodymanic side is not as much of an issue anymore, since the F-22 is generally seen as the stealthiest fighter, nearing the F-117 in RCS, but can take out anything in service right now in a dogfight.
		I saw a JDW article about the Russian plasma device, and as I've said before the 1st and 2nd generation of plasma stealth devices are for sale, according to the article.

		Plasma is the most common state of matter in the universe, it can carry electric currents, neutral particles and magnetic fields that exhibit collective effects.
		Plasma can disturb electromagnetic waves to the point of transforming them to differing frequencies scattered all across the RF spectrum, rendering the electromagnetic waves that encounter the plasma virtually useless.
		It is supposedly similar to a plasma TV screen made up of cells or rastars filled with neon, xenon or some other inert gas which is excited by an electrical current, and when there is no current going to the unit it is completely transparent to the Su-35's radar.

		The main drawbacks of the Stealth technology are its negative effects on the flight and agility characteristics of the stealth aircrafts.
		If an object is surrounded by a cloud of plasma, several phenomenas are observed when the cloud interacts with electromagnetic waves radiated by enemy radar.
		First, an absorption of electromagnetic energy occurs in the cloud, since during plasma penetration it interacts with plasma charged particles, pass onto them a portion of its energy, and fades.

		However, I really don't think plasma will be very steathly if it works like the plasma generators used in silicon wafer etching with which I am familiar.
		They uses a powerful RF transmitter to make the plasma, which should be able to be detected.
		But the plasma generator RF leakage seems to be a big drawback.

		Plasma is EXACTLY why the space shuttle is out of radio contact during re-entry.
		And while it is probably true that the B2 does not use any direct plasma-generateing techniques as suggested by jhaley, it is important to note that ALL stealth technologies EXCEPT redirection (reflecting microwaves anywhere but back to their source) use some form of stealth shielding technique.
		For a practical example of this fundamental principle (plasma stealth), you could place a lit candle in your microwave, and turn the microwave on.
