    Beginning with the next issue of these Transactions, Kiyo Tomiyasu will be the Editor. The last two years have seen these Transactions grow both in size and quality of contents. The growth has been a healthy one, and there appears to be every reason to believe that it will continue. In closing my term of office, I would like to thank the various people who have helped to make these Transactions po... View full abstract»

    Because of advances in communication, it has been said that more progress has been made in science and general living conditions in the last fifty years than in all the thousands of years preceding. Part of this is due to transportation improvements in all divisions--land, water, and air. Today, auto trips from New York to Chicago in about fifteen hours demonstrate strikingly what a big advance tu... View full abstract»

    Microwave theory and techniques include the transmission, control, and measurement of waves of centimeter or millimeter length. The methods applicable in this region differ sufficiently from those at lower frequency to constitute a rather well-defined discipline. This area is the subject of our review. Several subjects contiguous to the microwave domain are excluded. Thus, antenna and propagation ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (697 KB)

    A method is presented for determining the capacitance of electrostatic fields which have hitherto proved intractable because their solutions required the evaluation of hyperelliptic integrals. The method is illustrated by applying it to the determination of the characteristic impedance of a strip transmission line. The results compare favorably with the results of existing solutions. The method is... View full abstract»

    Analysis is given for the problem of reflection of a plane wave at oblique incidence on a wire grid which is parallel to a plane interface between two homogeneous dielectrics. It is assumed that the wire grid is a periodic structure and consists of thin cylindrical wires of homogeneous material. The equivalent circuit is derived where it is shown that the space on either side of the interface can ... View full abstract»

    The two-dimensional Hehnholtz equation is solved in a rectangle having two semicircular projections in the center of its broad faces. More particularly, the lowest two eigenvalues are determined for Nenmann's boundary condition, and the lowest eigenvalue for Dirichlet's boundary condition. The results are of interest in various fields of physics, such as vibrations of a membrane, but are of partic... View full abstract»

    This paper deals with the development of a new model for a class of microwave filters. With this model one can reproduce and systematize from a general viewpoint results now in the literature. Its most prominent feature, however, is that the use of the model permits the development of a synthesis procedure for the wide-band filter. From this single model a wide variety of structural realizations a... View full abstract»

  • Single Slab Arbitrary Polarization Surface Wave Structure

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (618 KB)

    A single grounded dielectric slab can support either TM or TE modes, but cannot propagate both with the same velocity. This paper concerns a modification of the single slab which enables either polarization to propagate with the same velocity. Such a structure could transmit a circularly polarized wave, and would be useful in transmission, feeder, and antenna applications. The structure consists o... View full abstract»

  • The Effects of Reflections from Randomly Spaced Discontinuities in Transmission Lines

    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (569 KB)

    Reflections from randomly spaced transmission line discontinuities can cause serious attenuation and distortion of pulses in the lines, and the presence of reflections at the sending end may be undesirable. The effect of these discontinuities may be described in terms of the mathematics for combining outputs from oscillators with random frequencies. The location of the discontinuity corresponds to...

    The problem ot predicting the probability distribution of vswr for many randomly spaced discontinuities is solved using the "central limit theorem." Assuming that reflection factors add in the complex plane and using the "central limit theorem" the result is shown to be a Rayleigh distribution in terms of the reflection factor. The probability of the vswr over a band of frequencies is calculated u... View full abstract»

    Because of growing applications of millimeter wave measurements, a fairly thorough investigation of what could be expected from sources and detectors in the 3 mm region was made. The sources consisted of fourth-harmonic generators from a 1.25 cm fundamental. A type of crystal holder for both harmonic generators and detectors in which a small crystal wafer is positioned in the broad wall of the mil... View full abstract»

  • Circularly Polarized Microwave Cavity Filters

    A new group of circularly polarized microwave cavity filters is described. With a single circularly polarized cavity, a reflectionless filter is achieved that couples nearly 100 per cent of the energy from the main waveguide at the cavity resonant frequency. Two degenerate cavity modes may be excited, to produce a circularly polarized field, by coupling to the transverse and longitudinal waveguide... View full abstract»

    The design problems in a reference cavity include coupling, cavity Q, temperature compensation, stability, and hysteresis. Temperature compensation is shown to be a problem in second order compensation theory and is solved by material changes. Stability is achieved by novel mechanical design and by elimination of hysteresis producing members. View full abstract»

    A procedure is presented for connecting some known physical applications of Fourier transform pairs in different branches of the theory of waves and circuitry. After an investigation of the cases of diffraction, reflection, and coupling of waves, deflection of particles (which includes the cathode-ray-tube case and so-called gap effect) and the closely related scanning problem are examined.

    Projective constructions are described for deducing the iconocenter of a two-port junction from input reflection coefficient measurements taken with a short circuit placed in various positions in the output waveguide. The wavelength in the ouput line is deduced from a four-point measurement. If this wavelength is known in advance, a three-point measurement gives all the information needed to const...

    On January 4, 1957, the IRE Board of Directors arrived at a decision which may in time prove to be one of the most far-reaching in its 45-year history. On that date the Board adopted a plan which will enable non-IRE members whose main professional interests lie outside the sphere of IRE activities to become affiliated with certain of the IRE Professional Groups without first having to join the IRE...

    I would like to call your attention to a certain error in the above correspondence. The admittance function plotted by the author on the Smith chart winds counter-clockwise. This is contrary to the laws of nature for passive linear networks. These laws prescribed that the plot of the admittance function wind clockwise from the low to the high frequency.
