Output of the transmitting antenna is produced by an electromagnetic wave that is radiated from conduction current in each of the first and second conducting wires. In another aspect of the invention, first and second spherical balls are connected by conducting wires to the collectors of respective charged particle beam vacuum tubes in which a charged particle beam gun produces a beam of finite length of electrons or ions within the vacuum tube that moves within the vacuum tube at a controlled speed to generate an electromagnetic wave.

Abstract: The present invention is a method and apparatus for receiving and converting incident radiation into DC current. The method begins with selection of an antenna having a terminal tip with a sharp edge. The antenna is layered with a substrate and a first coating. A first electrode and a metallic/mCNT antenna are layered on the first coating, and a plasmonic layer is then added. A gap is formed which is bounded on one side by the terminal ends of the plasmonic layer and the first coating, and a second electrode and a second coating on the other. The second electrode is layered upon the second coating which is layered upon the substrate. A set of AC currents is induced along the length of the antenna. The method then calculates whether or not the induced AC currents are large enough to create voltages for field emission. If the voltages are large enough, then a forward bias and a reverse bias are initiated. Due to the asymmetry in these tunneling barriers, a positive net DC current is delivered to an external circuit.

Abstract: A plasma generating apparatus is provided with an impedance matching member, which is connected to a feeding line that supplies an antenna element with a high frequency signal, and has variable characteristic parameters for impedance matching; a distribution wire, which is arranged corresponding to the impedance matching member and connects the impedance matching member with at least two antenna elements; and a control section which changes at the same time impedance matching statuses of at least the two antenna elements connected to the impedance matching member through the distribution wire by changing the characteristic parameters of the impedance member. Thus, the number of impedance matching devices is smaller than that of the antenna elements, and a mechanism relating to impedance matching is made relatively small.

Abstract: A plasma antenna includes a plasma column formed of an ionizable gas. A modulating carrier frequency produces Hertzian dipoles within the plasma that radiate RF energy at the modulating carrier. The antenna, which produces these dipoles, can be short and still produce significant gain when the modulating carrier frequency and the natural resonance frequency of the plasma are substantially equal. Other aspects of the invention include a method to produce such plasma antenna and a product by process embodiment of the plasma antenna.
