    Man's sophisticated art of communications has been built upon his ability to generate and detect coherent electromagnetic waves. This art has been pushed to higher and ever higher frequencies, until now important experimental work is being carried on in the neighborhood of one millimeter wavelength. View full abstract»

    This paper presents a systematic approach to the evaluation of (waveguide) junctions from the standpoint of their conformance to certain symmetries. Preferred sets of asymmetry parameters are found which are complete, minimal in number, which go to zero when the junction represented is symmetrical, and which may often be identified with a corresponding structural symmetry defect. The asymmetry par... View full abstract»

    A modfied reciprocity theorem forms the basis of development of orthogonality relationships for modes in waveguides and in cavities containing inhomogeneous, anisotropic media. In the lossless case certain of these may be interpreted in terms of power flow and energy storage. The special case of magnetized gyrotropic media is discussed for longitudinal and transverse magnetization. View full abstract»

    The treatment of mismatch errors is extended to cover variable attenuators cascade-connected in a system which is not free from reflections. The method of analysis is applicable to any number of cascaded attenuators, but only the analysis of two and three variable attenuators in cascade is presented. Graphs are given to aid in estimating the Iimits of mismatch error. In an example, which is consid... View full abstract»

    The theoretical and experimental operation of a novel form of TEM transmission-line network capable of operation over octave bandwidths is described. This network consists, basically, of a parallel arrangement of two conductors and a ferrite rod within a grounded outer shield. The conductors maybe connected in a two-port configuration which provides, in the absence of the ferrite rod, complete iso... View full abstract»

    In order to obtain filters capable of handling very high power, the use of radial lines and uniform line discontinuities was investigated. Forty-five-degree tapers and uniform lines were used to design a high-power microwave filter capable of handling 700 kw at 15 pounds pressure in a 0.900 by 0.400 ID waveguide. In addition to the filtering which results from the discontinuities in the TE10<... View full abstract»

  • A Method for Accurate Design of a Broad-Band Multibranch Waveguide Coupler

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (671 KB)

    A new approach is made to the problem of tapering the branch impedances for broad-band performance. A taper is proposed, which, for a 3-db branch coupler, is shown to give much better results in theory and practice than the currently used binomial taper. Also, simple expressions are developed which enable the effects of waveguide junction discontinuities to be adequately corrected, thus allowing a... View full abstract»

  • The Analogy Between the Weiss-floch Transformer and the Ideal Attenuator (Reflection Coefficient Transformer) and an Extension to Include the General Lossy Two-Port (Correspondence)

    Weissfloch's transformer theorem states that at certain pairs of reference planes a lossless two-port can be represented by an ideal transformer. There are many proofs of this important theorem. One of the most interesting is due to Bolinder, who uses properties of the bilinear transformation. For lossless two-ports, the transformations will belong to the Fuchsian group. View full abstract»

    Use of two tuning screws through the ground planes of a strip-line cavity resonator can excite the parallel plane TEM mode unless both screws are equidistant from the center conductor, rendering this method of tuning quite unattractive. A single tuning screw parallel to and midway between the ground planes is the better way of tuning a stripline cavity resonator. View full abstract»

    The recent advances in low-noise amplifier work for communications systems has created an additional demand for circulators; in this case, to prevent receiver noise from returning to the low-noise amplifier. In the range of frequencies greater than 2000 mc, ferrite circulators have been developed in circular and rectangular waveguides. However, in the UHF region, which is a range of frequencies of...

    Mr. Dettinger's article on the optimum spacing of bead supports in coaxial transmission lines is too sanguine as to the performance which will result. He states that an array of M beads arranged according to his theory will result in a total reflection coefficient of no more than /spl radic/M Gamma/sub 0/ where Gamma/sub 0/ is the reflection of one bead. In his Fig. 5 he shows a chart of the refle... View full abstract»

    Mr. Muehe's results for broad-band stubs, while going beyond that of previous investigators, are similar to my design curves published earlier without detailed derivation. The main difference is that my curves were based on a formula involving the bandwidth as defined by the lowest and highest frequencies of zero reflection. Mr. Muehe's analysis is therefore superior to my simpler approach: my des... View full abstract»

    The properties of the lowest order hybrid mode of the H-guide line have been analyzed by Tischer in a number of papers. This type of transmission line has also been under investigation at this laboratory for some time and a number of discrepancies exist between our analysis and those of Tischer. View full abstract»

    Let it be required to determine the guided wavelength in a dielectric-filled periodic structure, such as a corrugated wall or serrated waveguide. The accepted traveling probe technique requires a slot in the broad wall of the guide and a groove in the dielectric material. Even if the errors introduced by these modifications could be tolerated, other effects render this technique unsuitable, One of... View full abstract»

    The dielectric constant of low-loss dielectric materials can be measured accurately, rapidly, and automatically by proper utilization of an automatic microwave impedance instrument of the type which presents its output in Smith Chart form; i.e., the magnitude and phase of the reflection coefficient. The method employed is essentially a modification of the slotted line technique which was originall... View full abstract»

    The serrated choke described by Dr. Kiyo Tomiyasu and J. J. Bolus is a very effective device to employ whenever long cuts or gaps are present on the walls of rectangular waveguide. This communication is concerned with the application of a serrated choke to an X-band waveguide ring switch, wherein the waveguide was split longitudinally at opposite corners to form a rotor section and a stator sectio...
