Method and apparatus for altering a region in the earth's atmosphere, ionosphere, and/or magnetosphere

摘要: A method and apparatus for altering at least one selected region which normally exists above the earth's surface. The is excited by electron cyclotron resonance heating to thereby increase its charged particle density. In embodiment, circularly polarized electromagnetic radiation transmitted upward in a direction substantially parallel along field line extends through of plasma be altered. frequency excites heat accelerate particles. This energy can cause ionization neutral particles are then absorbed as part increasing density region.
