Abstract: A method and apparatus for generating microwave radiation includes a cathode, comprising parallel side wall means, a first end wall and a second end wall parallel to the first end wall, which defines a space. An aperture is defined within each of the end walls. An elongated anode extends across the defined space and outwardly through the apertures. Free electrons are generated adjacent to the anode and a positive potential is applied between the cathode and the anode. Electrons are trapped in a surrounding relation with the anode and microwave radiation is generated.

Abstract: A method of operating a plasma antenna, reflector, director, and barrier, where the plasma antenna is pulsed at a pulse power for a pulse duration and a pulse frequency to energize a plasma within the plasma antenna for an afterglow duration, where the pulse duration is shorter than the afterglow duration. In this manner, the power required to operate the plasma antenna is dramatically reduced, while the power at which the antenna operates can be dramatically increased. In addition, the antenna operates primarily in the low noise afterglow phase. Thus, several problems in regard to the prior art are overcome.

Abstract: An image viewing device is described which is capable of producing images comprising at least a 180° field of view, also referred to as fisheye images. The device employs an extremely small aperture in conjunction with an optical block comprised of a refractive material. The light rays from an image pass through the aperture whereupon they are compressed in angle by the optical block to produce the fisheye image. An optional image intensifier may be employed to enhance the image produced by the optical block. Additionally, optional filters, viewers, and recording devices may be employed to enhance the image produced as well as to provide a permanent record of any images produced. The image viewing device is capable of producing high resolution color, black and white, and monochromatic fisheye images under various weather and lighting conditions.

Abstract: A pair of electrodes are biased to produce an electrostatic discharge while placing a thin non electron absorbing gas layer near one or both of the electrodes which are used to develop the electric field. As a result, atmospheric oxygen, water vapor and other contaminants are removed from the regions surrounding the electrodes, allowing ionization to occur more easily. This is accomplished with an electrode structure including a hollow tube for receiving a gas, a plurality of apertures extending through the hollow tube for delivering the gas to the surface of the hollow tube, and the application of a biasing voltage for producing an electrostatic discharge in the presence of the gas. The tube can take the form of a longitudinally extending structure, or a hollow shell, depending upon the configuration of the electrostatic charging apparatus with which the electrode structure is used.

Abstract: Method and apparatus for removal of nonelectrically-conducting gaseous, liquid, and particulate contaminants from molten metal compositions by applying a force thereto. The force (commonly referred to as the Lorentz Force) exerted by simultaneous application of an electric field and a magnetic field on a molten conductor causes an increase, in the same direction as the force, in the apparent specific gravity thereof, but does not affect the nonconducting materials. This difference in apparent densities cause the nonconducting materials to "float" in the opposite direction from the Lorentz Force at a rapid rate. Means are further provided for removal of the contaminants and prevention of stirring due to rotational forces generated by the applied fields.

Optionally, an energy modifying medium to reconfigure the waveguide such that electromagnetic waves of various wavelengths may be propagated directionally along the path may be used. Similarly, these waveguides may be modified into coaxial configurations.
