    The omission from this issue of our distinguished microwave personality is regrettable. This feature has evoked much favorable comment and it is planned to continue it in all regular issues. The October issue will present Professor Ernst Weber of the Polytechnic Institute of Brooklyn. View full abstract»

    This paper describes the design and development of a double-ridge waveguide designed to propagate both C-band and X-band (5,400 and 9,300 mc) so as to allow for a common waveguide installation in commercial airliners which could use either a C-band or an X-band weather penetration radar. This double-ridge waveguide is capable of propagating over the desired frequency range with single mode operati... View full abstract»

    Generally, the calculation of antenna far-field patterns from known near-field distributions is tedious and may require the use of a large computer. The calculations are simplified for certain types of antennas having separable near fields. This simplifying assumption is found to yield satisfactory results with pyramidal horns and parabolic reflector antennas. Calculations are further simplified b... View full abstract»

  • A Modulated Scattering Technique for Measurement of Field Distributions

    Electric field distributions can be measured accurately by passing a short metal dipole through the field and recording the wave scattered by the dipole. Ordinarily the method is difficult to use since the scattered signal is small, critical tuning adjustments are required, and careful attention to stability is necessary. However, by placing a nonlinear impedance at the center of the dipole and ap... View full abstract»

  • Potential Solution of a Homogeneous Strip-Line of Finite Width

    The exact potential solution for a zero-thickness strip centered between two ground planes of finite width is outlined. For unit separation of the ground planes, the solution is applied to obtain curves of capacitance per unit length for several representative ground plane widths as a function of strip width. The results are valid for all strip widths, including the case in which the strip is wide... View full abstract»

  • Resonant Frequencies of Higher-Order Modes in Radial Resonators

    A summary of the relevant work on radial line discontinuities and radial line resonators is presented. A step-type discontinuity is analyzed using an integral equation formulation and the results are applied to the calculation of the resonant frequencies of a radial resonator. This method is verified by experiment and compared with the foreshortened-line approximation and with the methods of Marcu... View full abstract»

  • A Shunt Technique for Microwave Measurements

    A new method of measuring low-loss quantities at microwave frequencies, which employs a Iossy shunt structure, is described. The additional loss introduced thereby reduces the excessively high VSWR's to values lying in the measurable range. The relevant information is abstracted from the data in a precision manner independent of the parameters of the shunt structure itself. Applications are made t... View full abstract»

    This paper describes a rotary joint for two microwave transmission channels of the same frequency band. It consists of two pairs of rectangular waveguide terminals, a circular waveguide which transmits both channels, and coupling elements between the rectangular waveguide terminals and the circular waveguide which convert the rectangular H10 mode into the circular H01 and E...

    A coaxial line containing a medium of propagation consisting of two coaxial cylindrical cylinders of different dielectric constant is considered for the special case of TEnm resonances, and numerical calculations are carried out for a few cases of the TE11 type resonance. A reference paper called to the attention of the author by the reviewer treats the general condition of p... View full abstract»

  • The Operation of Bolometers Under Pulsed Power Conditions

    The dynamic behavior of Wollaston (thin platinum) wire bolometers under pulsed power conditions is examined and shown to be responsible for certain errors in the measurement of microwave power. These errors, in order of importance, arise from the nonlinearity of bridge null arm current as a function of bolometer resistance, from the nonlinear cooling of the bolometer in the interval between pulses...

    Questions frequently arise in Editorial Board discussions and among the reviewers of Proceedings papers as to what should be published in the Proceedings of the IRE and what should be published in the various Transactions. This statement will not settle the matter, but it does clarify the present situation and speculate about future possibilities. View full abstract»

    Matching an impedance to a transmission line by the use of a cascaded section of line is a well-known process. However, the range of terminating impedance that can be matched by this method, I believe, is not so well-known. Consider a lossless line of characteristic impedance R/sub0/ to which is to be matched an arbitrary impedance /bar Z/ = R + jX by means of another lossless line of lentgh d and...
