    Simple formulas are given for the characteristic impedance of a transmission line consisting of a conducting strip of rectangular cross section centered between parallel conducting plates at ground potential. The formulas agree to within 1.2 per cent with an exact formula for a zero thickness strip. In the case of finite thickness up to a quarter of the plate spacing, the formulas are expected to ...

    The Microstrip is a modification of the wire-above-ground system of transmission - the wire is replaced by a narrow strip printed on a dielectric sheet which is backed by a conductor. An exact theory for such a structure is difficult because the cross section is not homogeneous and has a geometry which does not lead to separation of variables. Furthermore it is an "open" structure where the energy... View full abstract»

    Very often in working with a waveguide transmission systems, it is necessary or desirable to couple off from the system a specified amount of the energy for various purposes. A common and practical method of accomplishing this is through the use of directional couplers and waveguide hybrid junctions. The hybrid junction, as used in this discussion, refers to a specialized waveguide directional cou... View full abstract»

    A coaxial hybrid junction is described whose performance is analogous to a waveguide magic-T. The design of three different types of coaxial magic-T is discussed. Standing-wave characteristics of an experimental model of each type are given. Experimental results indicate that standing-wave ratios less than 2 looking into any arm can be obtained easily over a frequency band of about 10 per cent. Ow... View full abstract»

    In the maintenance of ultra-high frequency equipments utilizing waveguide, one of the more difficult troubles to diagnose and correct is that of the high standing wave ratio. The question always arises as to whether the antenna or the waveguide is at fault. Sometimes a visual inspection of the transmission system will disclose the difficulty. Too often, however, the physical layout of the system m... View full abstract»

    In the past few years research with ferrites has shown that these materials possess unusual properties of considerable importance to microwave engineers. These properties result from the fact that at microwave frequencies and in the presence of a static magnetizing field, these non-conducting ferromagnetic media are characterized by an asymmetric tensor permeability whose components are functions ...

    An analysis has been made of a coaxial transmission line composed of two coaxial cylindrical conductors. Two dielectrics fill different angular portions of the volume between the conductors. The propagation constants (primarily the guide wavelength) are determined by a resonant condition applied to the plane transverse to the direction of propagation.

    A new use is made of the classical two-wire transmission line in its application to microwave transmission. By the introduction of a ground plane, the familiar two-wire line is reduced to a planar configuration which permits important advantages to be obtained compared to present microwave techniques. These advantages include good electrical characteristics, reduction in size and weight, with corr... View full abstract»

    Compandors are used to improve the intelligibility of speech transmission circuits by increasing the signal-to-noise ratio. Originally developed in the early 1930's for use with transoceanic radio circuits, they have since been applied to some extent on long distance telephone circuits, usually of the carrier-derived type. Within the past few years new telephone carrier systems have been developed... View full abstract»

    A calorimeter for measuring low-level power at millimeter wavelengths is described. This is a broadband device capable of measuring power levels of the order of one milliwatt with an estimated accuracy of plus or minus 1/4 db.

    In view of the important part played by rotary joints in many radar systems, it is surprising that little or nothing has been published on this subject since the appearance of the discussion by Niemann, Ehlers and Worrell, in which they give the war time status of this component. In spite of the excellent work already done on this project, however, there remained a need for a high power rotary joi... View full abstract»
