    Born at Vancouver, Washington, on June 17, 1905. Mr. Mumford majored in physics and mathematics at Willamette University, Salem, Oregon, receiving the A.B. degree in 1930. He at once joined the Technical Staff of the Bell Telephone Laboratories with the Radio Research Department at Holmdel, N. J. He has worked on ultra short-wave propagation and microwave components for radio relay systems and rad... View full abstract»

    Microwaves are playing an ever-increasing role in the communications field. Over 30,000 route miles are already being used in the United States by communication companies, industrial and transportation concerns and the military agencies. Bell System microwave facilities alone provide more than 6,500,000 miles of telephone circuits and 48,000 miles of television channels. Thousands of miles of addi... View full abstract»

    The field of interest indicated by the title includes the transmission, control, measurement, and generation of microwaves. We shall consider transmission only in the form of guided waves, leaving antenna and propagation problems as a subject deserving of a review in its own right. Similarly, we shall take note of the circuit aspects of microwave amplifiers and generators. Space charge, focusing, ... View full abstract»

    This paper derives formulas for the transmission properties--characteristic impedance and attenuation--in the principal mode of a transmission line consisting of one or two long strips of metal foil embedded in a dielectric material between two long metal strips considerably wider than the central ones. The width and spacing of the central strips is arbitrary, and it is also necessary to take acco... View full abstract»

  • Measurement of Time-Quadrature Components of Microwave Signals

    A phase-sensitive coherent detector used for microwave laboratory measurements is described. The receiver measures the real (|E| cos alpha) and imaginary (|E| sin alpha) components of a signal E with equipment which is less elaborate than that required for measuring the amplitude |E| and phase alpha. Furthermore, many calculations are more convenient if E is presented in rectangular rather than po... View full abstract»

  • Optimum Design of Stepped Transmission-Line Transformers

    This paper describes the optimum stepped-transmission-line transformer structure for matching two unequal characteristic impedances. For any specified bandwidth, the steps are designed to yield a Tchebycheff-type (or equal-ripple) reflection-coefficient response. Over this band, the maximum vswr is less than that obtainable with any other stepped-transformer having the same number of steps. Design... View full abstract»

  • The Use of Scattering Matrices in Microwave Circuits

    Publication Year: 1955, Page(s):21 - 26

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (626 KB)

    Difficulties arising from the use of the impedance concept in microwave circuitry have led to the introduction of the scattering representation for work at these frequencies. This paper presents a development of the scattering approach in terms of fundamental transmission-line phenomena. The physical meaning of the quantities involved is brought out wherever possible and the relationships among th... View full abstract»

    This paper describes the use of ferrites in waveguide to produce Faraday rotations at 0.87 cm and 1.9 cms wavelengths. The Dicke radiometric receiver is briefly reviewed and its improvement by the use of ferrite waveguide components is described. Experimental equipment for securing data on the behavior of ferrites is discussed. Details are given for the construction of a unidirectional waveguide t... View full abstract»

  • Probes for Microwave Near-Field Measurements

    Publication Year: 1955, Page(s):32 - 34
    Cited by:  Papers (16)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (292 KB)

    To be satisfactory for microwave near-field measurements, a probe must have desirable polarization characteristics, must have an aperture small enough to indicate the field at a point, must deliver sufficient signal voltage to permit accurate measurement, and yet must not seriously distort the fields. The design of a probe may be simplified if the fields to be measured are known to be almost linea... View full abstract»

    This paper surveys some of the techniques that have been worked out for multimode waveguide measurements. Equipment has been developed for measuring one mode at a time by taking advantage of the differences between the modes. Illustrations of its use are given. View full abstract»
