    Born in Russia in 1915, in Ekaterinoslav, now Dnepropetrovsk, Edward L. Ginzton came to the United States when he was 13. He attended the University of California, receiving the B.S. and M.S. degrees in electrical engineering. With the encouragement and assistance of Dr. F. E. Terman, he transferred to Stanford University for graduate work in radio engineering, receiving the E.E. degree in 1938 an... View full abstract»

    Many of us are so immersed in the ever-narrowing branches of electrical engineering that it is difficult to take stock of the accomplishments in the field as a whole or to visualize the possibilities and limitations of future developments. For those of us engaged in teaching and research, and who expect to remain in the field, such an assessment is necessary if we are to guide our students properl... View full abstract»

    The problem of evaluating dielectric constant and loss tangent by the short-circuited-waveguide technique has been encountered continually in recent years in the study of artificial dielectric media and radome materials. In general, practical measurements have involved materials with low loss and dielectric constants less than 10. The analytical method normally applied to data on such materials re...

    A solution to the problem of propagation of higher modes in a transversely magnetized ferrite-filled rectangular waveguide has been found. The solutions to the problem are expressed in the form of four rigorous nonlinear algebraic equations which characterize the problem and are ready for numerical solution. The dependence of the fields in the direction of magnetization is the same as for the clas... View full abstract»

    The nature of the electromagnetic field of an antenna in the vicinity of a surface of large radius of curvature is discussed. Assuming a spherical surface, the solution for a dipole source in the form of the Watson residue series is transformed to a more rapidly converging series which is preferable at short distances. Using this result, numerical data is presented in graphical form for the curren... View full abstract»

    The effective noise temperature of the output impedance of a Iossy passive network at an arbitrary noise temperature connected to one or more resistive loads at arbitrary noise temperature lies between the highest and the lowest of these noise temperatures, as determined by the losses between the output terminals and the loads. The determination of the effective noise temperature of a gas-discharg... View full abstract»

    This paper describes a single-sideband modulator for shifting the frequency of an x-band signal by means of a rotating magnetic field transverse to a ferrite differential half-wave section. The device is one of the first practical applications of the double-refraction properties of ferrites. Improvements over an earlier model include reduction in size and continuous operation without drift. An eff... View full abstract»

    Cited by:  Papers (10)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (799 KB)

    An array of parallel metallic plates of finite thickness are useful in microwave lenses. The effect of finite thickness in the idealized situation of a semi-infinite array of perfect conductivity, is treated theoretically and experimentally for normal incidence of a uniform plane wave on the plane interface separating the medium from free space. The theoretical discussion involves the approximate ... View full abstract»

    A variational method is used to develop an expression for the characteristic impedance of a "trough line" consisting of a circular cylinder mounted inside and parallel to the walls of a semi-infinate rectangular trough. The "slab line" consisting of a circular cylinder between infinite, parallel plates is treated as a special case of the trough line in which the bottom of the trough is taken to be...

    During the evaluation measurements of several two-port junction devices over a wide band of frequencies the authors found that the method of shorts as described in three previous papers was too laborious to be practical. By reinterpreting and combining the ideas of earlier authors, a valuable simplification was obtained. Since this paper is based upon the previous articles, no fundamental proofs w...

  • Impedance and polarization-ratio transformations by a graphical method using the isometric circles

    The isometric circles for the direct and inverse linear fractional transformations can be used for transformations of impedances and polarization ratios. In the Ioxodromic case an inversion is performed in the isometric circle of the direct transformation, followed by a reflection in the symmetry line of the two circles, and a rotation around the origin of the isometric circle of the inverse trans...

    This paper describes a broad-band dual-mode waveguide transducer designed to couple two orthogonal TE11 circular waveguide modes in separate rectangular waveguide ports. A compact, rugged, and economical junction has been developed to operate from 8600 mc to 9600 mc with a vswr of less than 1.15 at the rectangular port and a mode isolation of 50 db or greater. Developmental models are d... View full abstract»

    The method of measuring cavity parameters outlined in the above paper has been used successfully for some time by our laboratory for measuring parameters of cavities at X band having Q's as high as 150,000. For improved accuracy in these measurements, an additional refinement has been made in the method which makes all measurements independent of the law of the crystal detectors used.

    I would like to call your attention to a certain mistake in the above paper. Park's transmission line, consisting of two parallel strips between two wide plates [Fig. 1(a)], has to be changed to the line geometry indicated in Fig. 1(b) in order to maintain the results of the mentioned paper.

    A variation on the method described by Feller and Weidner for abtaining low standing wave ratios over a frequency band has proven to be very useful in the design of low vswr microwave components. If curve A in Fig. 1 represents the input admittance of the device to be matched, the method described by Feller proceeds as follows: 1) Insert a value of susceptauce which causes the curve to lie along a...

    This book was written by the well-known American specialist in the uhf field who was one of the pioneers of waveguide techniques. As the author mentions in his preface, the book does not pretend to encompass fully the subject; however, in addition to a description of the fundamentals of the theory of waveguide transmission it contains extensive material devoted to the design and operation of vario...

    I should like to take advantage of this correspondence column to discuss briefly a problem which we at Clarkson College may have in common with many other private colleges. We believe that our undergraduate curriculum should include a course in microwaves and that this course to be effective must include some laboratory work. The problem is that it is very dificult to equip a microwave laboratory ... View full abstract»
