    In the face of rapid strides in microwave technology it is appropriate to review from time to time the part played by these Transactions. Through an understanding of what the Transactions On Microwave Theory And Techniques can and should do, we may make better use of what we now have, and improve it in the future as well. What, then, do we aim for in our six issues each year? View full abstract»

    An X-band ruby traveling-wave maser (TWM) has been constructed and tested in which the RF structure is a double-ridge ladder line and the signal is coupled into and out of the structure with coaxial lines. The pump power is propagated in a waveguide mode and the device is operated at and below liquid helium temperatures. A four-inch electromagnet was used. The TWM was operated at the push-pull poi...

    An unknown load impedance terminating a lossy two-port junction can be calculated if the input impedance and junction parameters are known. It is to be shown that there exists a linear relationship, dependent upon two calibration constants, between the input reflection coefficient and a modified reflection coefficient of the load. Applying the linear transformation to the junction input impedance ... View full abstract»

    This paper presents criteria for designing nonreciprocal coupled-wave devices which may be used as isolators, circulators and duplexers. An experimental model of such a device was designed and tested over a 6 per cent frequency band centered at 35 kMc, and the obtained data are in good agreement with the theory. Such devices should have numerous applications as they offer the capability of operati... View full abstract»

    The Wiener-Hopf tectilque is used to obtain an exact solution to a two-dimensional scattering problem. In the problem solved, an incident TE10 mode, traveling from z= -∞ in the positive z direction, is confined by infinite bounding planes; these planes have infinite conductivity for z<0 and an impedance Z1, for z>0. The scattering from the junction at z=0 gives ri... View full abstract»

    A new measurement technique is described that records the ferromagnetic saturation curve in a way that permits the Suhl critical field to be evaluated directly from the recording. This technique eliminates the tedious task of constructing point by point saturation curves for evaluating the critical field and shortens immensely the time required to determine spinwave linewidths from the saturation ...

  • Frequency Doubling Using Ferrite Slabs, Particularly Planar Ferrites

    An analysis is given of the results of frequency doubling experiments using relatively thick ferrite slabs. The primary frequency was 9100 Mc. It is shown that the dielectric properties of the ferrite cause the double-frequency wave to behave as a surface wave. This tends to concentrate the double-frequency fields in the vicinity of the ferrite, thus increasing its interaction with the oscillating... View full abstract»

    The helix-coupled, coaxial, gaseous noise source poses a burnout hazard to tunnel diodes unless certain precautions are taken. The attached oscillograms illustrate the transient in question. Typical short-circuit peak currents are 300 ma. The transient is a consequence of the sudden forced transition of the helix core from a nonconducting, unionized gaseous media to that of a conducting plasma. Th... View full abstract»

    For operation of parametric amplifiers at low frequencies and at low-impedance levels a parametric diode of very large capacitance is necessary. In general a capacitance which has an impedance of the same order as the source impedance is required, so that for a 600-ohm system at a frequency of 5 kc the static capacitance C0 should be C0
