    Slots laid broadside to each other exhibit mutual coupling of such magnitude that the design of practical linear arrays of such slots has hitherto been difficult, if not impossible. The technique presented here will produce arrays capable of generating pencil beams or shaped beams with controllable side-lobe level. A large number of slots per wavelength are used and the mutual-coupling effects are... View full abstract»

    When two complementary sources are combined in the proper amplitude and phase, desirable radiation characteristics for feeding a circular aperture are obtained. It is shown that when the feed is achieved there results a circular beam cross section which optimizes the efficiency of illumination of a circular aperture. The back radiation from the feed is down 30 db from that in the forward direction... View full abstract»

    Three types of transmission lines are analyzed, and it is found that the principal wave is not transverse electromagnetic in transmission lines for which the medium between the conducting boundaries is other than a homogeneous isotropic dielectric. Calculations of characteristic impedance and velocity of propagation on the basis of electrostatic and magnetostatic field distributions are accurate i... View full abstract»

    A theoretical analysis of the radiating properties of the paraboloid reflector and the hyperboloid lens shows that low amplitude cross-polarized radiation and high gain factors can be obtained from a paraboloid reflector excited by a plane-wave source. Low amplitude, cross-polarized radiation can also be obtained from the hyperboloid lens with a plane-wave feed, but with a lower gain factor. It is... View full abstract»

    The portion of a spherical Luneberg lens contained between two plane reflectors has been investigated as a lens of reduced size and weight. If the reflectors pass through the center of the sphere, the resulting system produces several perfectly focused radiation beams each appearing to originate from a virtual source on the surface of the full sphere. The virtual source positions and the position,... View full abstract»

  • A theoretical and experimental study of the recombination coefficient in the lower ionosphere

    Publication Year: 1954, Page(s):99 - 102
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (408 KB)

    The problem of recombination of electrons and ions in the lower ionosphere is studied both experimentally and theoretically. The experimental study involves analysis of new experimental data such as 150-kc radio wave absorption, polarization, and phase heights; absorption of short-wave galactic radiation; and E-region critical frequency, as well as recombination values already published. Then, by ... View full abstract»
