    This issue completes our first year using our new type and format. In the past year we have published four regular issues of the Transactions and the special issue on Microwave Strip Circuits. Our success is best measured by the quality and number of papers submitted for publication. The year's end marks a new policy. We will be able to prepare future manuscripts sufficiently far in advance to all... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (265 KB)

    Dr. Weber was born in Vienna, Austria, on September 6, 1901, and received all his education there. He was graduated with the diploma of Electrical Engineer from the Technical University in Vienna in 1924, and joined the Austrian Siemens-Schuckert Company as research engineer. On the basis of several papers on field theory applied to machinery, he received the degree of Sc.D. from the Technical Uni... View full abstract»

    Engineering endeavor is generally recognized to be the utilization of man's knowledge with ingenuity for human welfare. Man's knowledge is science in all its branches; ingenuity, art, inventiveness, creative application. With the increased scope of scientific exploration and discovery, engineering at the advanced stages has naturally become "scientific engineering." Perhaps no field has experience...

    Values of R/Qf or re-entrant resonators are given for configurations for which neither the coaxial-field nor the radial-field approximations are valid. The values are calculated by net point methods, and agree well with experimental values obtained by perturbation methods. Some errors arising from the finite dimensions of perturbing plungers are also discussed. View full abstract»

  • A High-Speed Broadband Microwave Waveguide Switch

    Publication Year: 1955, Page(s):11 - 14
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (798 KB)

    A switch which switches microwave energy to any of several separate waveguide loads is described. The switch has the bandwidth and power-carrying capability which is essentially that of the input and output waveguides. Data is given for a switch which operates over the frequency range of 8,600 to 10,000 mc with a vswr of less than 1.15 during transmission and less than 1.5 during switching. The sw...

  • Effect of Ellipticity on Dominant-Mode Axial Ratio in Nominally Circular Waveguides

    Publication Year: 1955, Page(s):15 - 20

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (449 KB)

    An investigation is made of the effect of ellipticity on the dominant-mode axial ratio (AR) in nominally circular waveguides. Equations for calculating the AR are derived for the case where the difference between the major and minor axes of the guide cross section is small and the waveguide is not too long. Values of AR obtained by calculations are compared with measured values, and a method for i... View full abstract»

  • The Design of Ridged Waveguides

    As far as we are aware, the only published design information on ridged guide transmission lines is found in a paper by S. B. Cohn and to some extent in the Waveguide Handbook. Recent applications, however, have indicated a need for additional and, in some cases, more accurate design information. The present paper is largely written with this in mind. View full abstract»

    An analysis is made of the odd and even TEM modes on a pair of parallel co-planar strips midway between ground planes. Rigorous formulas are presented for the case of zero-thickness strips, while approximate formulas are given for strips of finite thickness and for strips printed on opposite sides of a thin dielectric sheet supported in air between ground planes (AIL construction). The characteris... View full abstract»

  • High-Power Ferrite Load Isolators

    Publication Year: 1955, Page(s):38 - 43

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (774 KB)

    The principles of ferromagnetic resonance have been well described in literature. It is the purpose of this paper to point out the application of these principles to the design of practical microwave components, especially for high power. The various types of ferrite microwave circuits that can be used in the design of a load isolator are presented. The advantages and disadvantages of each of thes... View full abstract»

  • Step-Twist Waveguide Components

    The step twist is a number of adjoining sections of straight rectangular waveguide, twisted about their common axis at their junction faces. The technique of designing the step twist resides in the proportioning of the section dimensions and the angles at the twist faces. The resulting design is much shorter than the usual twisted waveguide; it offers further advantages in ease of specifying shape... View full abstract»

    The double-ground-plane strip line consists of two parallel conducting planes with a conducting strip imbedded in a homogeneous dielectric between them. Transmission characteristics for this system are calculated, and design formula are given. Practical viewpoints on design and application of strip lines are discussed. System can be used as an inexpensive base for microwave circuits and is well ad... View full abstract»

  • Transmission Characteristics of Sandwiches (Correspondence)

    The radome design equations which are in common use are based on the transmission characteristics of sandwiches. Transmission line techniques provide a convenient method for determining these characteristics. The transmission line analogy of wave propagation has been discussed by Ramo and Whinnery. A restricted application of this analogy is given in a report by Snow. In this note, a more general ... View full abstract»

    Often it is not convenient to measure a reflection coefficient directly. In some such cases, the following procedure may be used. The arrangement of components shown in Fig. 1 will be considered. It will be assumed that lines Nos. 1 and 2 are lossless. These lines may be transmission lines, waveguides, or one of each. View full abstract»
