20080317207Remote Communication Method and Device Unsing Nuclear Isomers - The invention relates to a method and device which are intended for remote control and communication using nuclear isomers. Several samples of nuclides that can have a metastable state are irradiated together and simultaneously with cascade gamma-rays emitted from a radioactive source or a particle accelerator. According to quantum mechanics, the gamma-rays produced are entangled, and said entanglement is transferred to the nuclear isomers. When the samples are separated and one of said samples, namely the master, is stimulated using a standard gamma- or X-ray irradiation method, the other samples, namely the slaves, are also deexcited. There is no known method for interference between the masters and slaves. Only the slave(s) can receive the signal instantly from the master through any medium and over any distance. The method and device are particularly suitable for communication and control applications.12-25-2008

20120288065Compact Coherent Current and Radiation Source - Coherent electronic current, which can be used to generate coherent radiation, is generated by first generating and transmitting an array of discrete electron beamlets from a nanocathode array along a longitudinal axis. The array of electron beamlets is then focused to reduce the spacing that separates the electron beamlets. The transverse-axis spacing of the electron beamlets is then transferred to the longitudinal axis via an emittance exchange beamline, creating a periodically modulated distribution of coherent electronic current. The coherent electronic current can then be directed into a stream of photons to generate coherent radiation.11-15-2012

This superconductor takes x amount of electro-magnetic energy waves and concentrates them by expulsion into an extremely powerful non-dissipating enhanced Faraday rotated directional output. This expulsion field, since it surrounds a central point in space because of the inner surface of a tube, is concentrated energy in a small space. Thus, it is impulsive and also induces ultra-Faraday rotation effect. In example, instead of Faraday rotation speed of energy wave rotation, the rotation field is much, much faster because of the superconductive Meissner field.10-08-2009
