A pseudo surface microwave produced plasma shielding system is a simple device that creates a prescribed plasma environment with a prescribed plasma density gradient, and protects an object surrounded by this environment as a shield. Pseudo surface microwaves interacting with an artificial intelligence equipped on board are used to create and to adjust this plasma environment for a particular application. This plasma environment provides potential capabilities of military applications of the plasma in the system. Examples of military applications include a stealth system from RADAR and SONAR, a protection system from WMD, and a weapon system to generate and launch plasmoids as a plasma gun. The scope of this invention extends to commercial applications of this plasma shielding system as a conditioned and controlled flow field, for example, a boundary layer and turbulence control system, and a lift control system to improve flight performance and flight economy of aircrafts. It further extends to develop a concept of a new type of engine using this plasma shielding system as a heating method alternative to the conventional combustion method that uses petroleum based fuel in the combustion chamber of an engine.
