    It is an exciting experience for an individual to participate in the birth of a new technological discovery and then to live to see it develop from infancy into a mature and important factor in the world. Such an experience comes unexpectedly to only a few lucky individuals and then usually once in a lifetime. I have always considered myself fortunate to have shared this kind of experience with a ...

    A microwave circuit is presented which provides continuous variation of microwave power between two outputs in any desired ratio. A typical device utilizing the circuit is described, and other uses of the circuit are discussed. An X-band power divider was constructed which had a vswr of less than 1.2 at all times over the frequency range of 8.6 to 9.6 kmc, divided the total input energy between th... View full abstract»

    The Faraday rotation and insertion loss of various ferrite-loaded waveguide structures have been studied in order to determine their power-handling capacities. A method of measuring insertion loss to within +-0.05 db is described. Two figures of merit containing this information are defied for the various configurations. The first, defined as the rotation per attenuation, indicates for a given val... View full abstract»

    A procedure for the design of aperture-coupled Filters is presented, based on the theory of conventional coupled circuits. This design procedure accounts for the relatively low insertion loss of aperture-coupled filters as compared with other known designs of microwave filters. The factors which contribute to this low value of insertion loss are the following: 1) Use of a high Q-mode configuration... View full abstract»

    This paper makes use of the higher mode limitations on the dimensions of symmetrical strip transmission line to derive the permissible dimensions at any given frequency and characteristic impedance. In conjunction with Cohn's results for the attenuation in strip transmission line these are used to obtain the maximum achiew able Q at any frequency and the optimum characteristic impedance; that is, ...

  • Deflection of Waveguide Subjected to Internal Pressure

    The pressure carrying capacity of a large range of standard waveguide sizes can be readily determined by the use of formulas presented in this paper. The derivation of these formulas is obtained by a contiguous beam analogy and comparable test results are shown which substantiate the validity of the theoretical analysis. Where high pressure conditions prevent the use of standard waveguide, these s... View full abstract»

  • The Calibration of Microwave Attenuators by an Absolute Method

    A bridge method by means of which microwave attenuators can be calibrated absolutely is described, with a consideration of the main possible sources of error. A bridge was set up at lambda0 = 3.2 cm to test the principle of the method. It was shown that, using nonspecialized equipment, a high degree of accuracy was obtainable. An attenuator was calibrated over a range of 20 db, with an ... View full abstract»

  • Pulse Waveform Degradation Due to Dispersion in Waveguide

    Publication Year: 1957, Page(s):254 - 257
    Cited by:  Papers (38)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (314 KB)

    Phase velocity in a waveguide is a nonlinear function of frequency and thus causes dispersion of the spectral components in a pulse waveform. For most practical cases, it is a good assumption to consider the phase constant to be a quadratic function of frequency. An expression can then be derived for the exit waveform shape as a function of guide length, dispersion, and width of the input rectangu... View full abstract»

    Analytical expressions are given for the propagation constant for the two orthogonal dominant modes in a square waveguide loaded with a centered slab of dielectric. These are combined to find the differential phase shift in a loaded section. Solutions of these equations are given for polystyrene which enables one to design broad-band quarter wave plates. The problem of transforming from unloaded t... View full abstract»

    This paper describes an investigation of the coherent microwave emission from pulse-excited ammonia molecules. Coherent and periodic pulses of near resonance frequency and 1-µsec duration excited the gas from its initial thermal equilibrium condition. Self-induced coherent emission (molecular ringing) continued after the excitation field was removed. This radiation was observed during a perio... View full abstract»

    In traveling-wave resonant ring circuits wave amplitude "amplification" has been predicted and shown experimentally. In the present note, the input reflection coefficient (input vswr) and wave amplification are considered when the resonant ring circuit contains a mismatch. Qualitatively a small mismatch (low vswr) can produce under resonant conditions a greatly "magnified" input vswr and reduces t... View full abstract»
