A method and apparatus altering a region of plasma that lies above the earth's surface at altitudes (e.g. below 50 kilometer) where the collison rate of the electrons in the plasma is originally greater than the cyclotron frequency of the electrons. First, artificial magnetic lines of force are established from the earth's surface by positioning a loop of cable at the earth's surface. An electrical current of sufficient amperage is passed through the cable which inherently generates the artificial magnetic field from the center of the loop. The field strength B on the artificial lines in the region of plasma to be altered is sufficient to increase the cyclotron frequency of the electrons in the plasma so that it will exceed the rate of collosion of the electrons. The plasma is then excited by electron cyclotron resonance heating to thereby further alter the plasma by transmitting circularly polarized electromagnetic radiation upward in a direction substantially parallel to and along the artificial field lines.
A method for forming a cloud of artificial ionization above the earth by initially heating the resident plasma at a desired altitude with electromagnetic radiation having a frequency approximately the same as that of the ambient plasma. As the plasma frequency increases due to heating, the radiation frequency is also increased until the final maintenance frequency is attained.

A system and method for power beaming energy from a source at high frequencies and rectifying such energy to provide a source of DC energy is disclosed. The system operates at a frequency of at
least 10 GHz and incorporates a rectenna array having a plurality of rectenna structures that utilize circuit elements formed with microstrip circuit techniques.
This invention relates to generation of a Artificial Ionospheric Mirror (AIM), or a plasma layer in the atmosphere. The AIM is used like the ionosphere to reflect RF energy over great distances.
A tiltable AIM is created by a heater antenna controlled in phase and frequency. The heater antenna phase shift scans a beam to paint a plasma layer. Frequency is changed to refocus at
continually higher altitudes to tilt the plasma layer.
An apparatus and method for performing geological mapping utilizes an HF transmitter to heat ionospheric electrons to cause the current in an overhead electrojet to be modulated, thereby injected a low frequency EM signal into the Earth-ionosphere waveguide. A sensor measures vector values of electric and magnetic fields in an area to be surveyed. The measured vector values are provided to a processor that creates a conductivity map of the surveyed area based on the measured vector values.
A plasma antenna is provided having an ionizer, which when energized, generates a bounded or unbounded plasma column extending along a vertical axis. When ionization is initiated, the difference in the diffusion characteristics of ions and electrons and the resulting gas plasma produce a current pulse in a first direction. As the plasma extinguishes, the difference in relaxation times for the ions and electrons in the plasma produces a second current pulse of opposite direction. The alternating current pulses generate an electric field that radiates from the plasma column.
This invention is a method and apparatus for creating artificially ionized regions in the atmosphere utilizing ionization trails of cosmic rays and micro-meteors to ignite plasma patterns in electric field patterns formed by ground based electromagnetic wave radiators. The applications are useful for telecommunications, weather control, lightening protection and defense applications. The invention lowers the power requirements for forming artificial ionized regions in the atmosphere by a factor of up to 1600 times lower than those required in existing designs and projections for creation of artificial ionized regions in the atmosphere.
