    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (645 KB)

    The effect of ambient-temperature variations on the running voltage of a glow-discharge reference tube is considered. Previous theories by Jurriaanse and Benson and Chalmers have been modified to provide a new and more accurate method of calculating temperature coefficients of running voltage. To verify the theory it has been necessary to determine running-voltage changes with tube current for dif... View full abstract»

  • A wide-band jig for the measurement of the current gain of transistors in the frequency range 20-1000 Mc/s

    Publication Year: 1963, Page(s):35 - 40
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (717 KB)

    The paper describes a jig primarily intended for the rapid measurement of the modulus of near-shortcircuit current gain of transistors in the frequency range 20¿1000 Mc/s (though phase can also be measured if suitable phase-comparison gear is available). The jig needs no internal tuning adjustments and uses 5 ¿ terminating resistors, so that the corrections needed to give true short-circuit curr... View full abstract»

  • The derivation of magnetron-output equivalent-circuit constants by probe measurements

    Publication Year: 1963, Page(s):41 - 50
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (927 KB)

    In connection with an investigation of r.f. discharges in magnetrons the measurement of interconductor voltage and lead current in the magnetron output by comparative methods using capacitive and loop probes is discussed. In practice loop-probe measurements are difficult to interpret, and an estimate of the current may not be possible. Some uncertainties may be avoided by representing the magnetro...

  • A tunnel-diode analogue and its application

    Publication Year: 1963, Page(s):51 - 63
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1453 KB)

    The investigation of switching and oscillation phenomena in tunnel diodes has a number of problems associated with it, one of which is the practical difficulty of observing the resulting fast waveforms. The analogue described in the paper facilitates the observation of these waveforms by slowing them down by several orders of magnitude. The parameters of the analogue are easily variable, thus enab... View full abstract»

  • A very-low-frequency transmission measuring equipment for 10-3-10-2 c/s

    Publication Year: 1963, Page(s):64 - 70
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1056 KB)

    The problems of measuring transmission (i.e. gain and phase shift) at frequencies in the range 10¿3¿102 c/s are briefly reviewed, and an equipment which overcomes most of them is described. The oscillator is novel, and has the important property that its amplitude is immediately self-stabilizing. The phase-shifter is also novel, and is of a resistive-potentiometer type having a set of ganged bru... View full abstract»

  • Waveguide for long-distance communication. A swept-frequency method for automatic recording of waveguide attenuation

    Publication Year: 1963, Page(s):71 - 76
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (646 KB)

    A common method of measuring characteristics of waveguides for long-distance communication involves the use of millimicrosecond pulses in a multiple-reflection test; test waveguides of a few hundred feet in length are employed. The enormous bandwidth, typically 40 Gc/s, which must be covered constitutes a major difficulty because several thousand measurements are necessary if the guide is to be ad... View full abstract»

  • Reactive effects in transverse-film bolometers in rectangular waveguides

    Publication Year: 1963, Page(s):77 - 78
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (258 KB)

    Lane and Evans have reported measurements on transverse-film bolometers and have analysed these to obtain values for the inductance of film. Their inductances are about 15% below those predicted by normal waveguide theory. It is shown in this paper that the discrepancy can be attributed to the presence of a capacitance associated with the glass strip on which the film is mounted. A further complic...

  • High-frequency radiation pressure and Hall effect in semiconductors

    Publication Year: 1963, Page(s):79 - 84
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (758 KB)

    The paper discusses high-frequency Hall effect as the counterpart of that portion of the radiation pressure which arises within a material medium when an electromagnetic wave is propagated through it. Radiation pressure due to reflection of the wave at the surface of the medium, when surrounded by free space, can have no counterpart Hall effect. In a previous paper the author showed that, in gener... View full abstract»

  • A microwave electrostatic wattmeter

    Publication Year: 1963, Page(s):85 - 87
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (306 KB)

    The paper describes an instrument incorporating a metal vane suspended in a waveguide as a means of measuring the power transmitted. The arrangement is electrically equivalent to the electrostatic wattmeter, well known in low-frequency applications, and in principle it has the particular merit of being able to record true power consumed by a load over a wide range of standing-wave ratio. The vane ... View full abstract»

  • A note on diffraction theory and polarization

    Publication Year: 1963, Page(s):88 - 90
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (253 KB)

    The plane-wave method of calculating the field radiated from an aperture has two forms depending on whether the source is taken as the tangential electric or magnetic field. The Huygens¿Kirchhoff method is intermediate between them. There is an apparent inconsistency in the predicted polarization of the distant fields; this is shown to depend on aperture-field terms usually neglected, and measure... View full abstract»

  • Theoretical characteristics of radiation reflected obliquely from a rough conducting surface

    Publication Year: 1963
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1314 KB)

    A theoretical estimate is made of the amplitude, phase, angular distribution and polarization of the radiation reflected from a rough surface when it is illuminated by an obliquely incident, plane electromagnetic wave. The surface is assumed to be made of perfectly conducting material and to be rough in one direction only (i.e. corrugated). In part of the paper a simple model rough surface is used...

    Cited by:  Papers (21)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (684 KB)

    A method is given for investigating the behaviour of electromagnetic fields in a homogeneous, anisotropic medium characterized by a dielectric tensor which is diagonal, with two of the three diagonal elements equal. It is shown that each such field is related by a simple scaling procedure to a corresponding vacuum field. The vacuum field is expressed as the superposition of a transverse magnetic f...

    Cited by:  Papers (7)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (513 KB)

    The problem is considered of representing the vacuum electromagnetic field of an arbitrarily orientated dipole as the superposition of coplanar transverse magnetic (TM) and transverse electric (TE) fields. The method is to express the dipole field as an angular spectrum of plane waves, and to introduce the appropriate representation of each plane wave of the spectrum. For a time-harmonic electric ...

  • An engineering study of the helical aerial

    Publication Year: 1963, Page(s):112 - 116
    Cited by:  Papers (5)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (581 KB)

    A theoretical study of the helical aerial is made assuming that waves travel both axially and helically along it. It is shown that the existence of the helical waves is responsible for what are defined as low- and high-frequency cut-off points of the aerial. Consideration is also given to the effect of the ground plane of the aerial on its radiation pattern. View full abstract»

  • A crystal mixer for c.w. radars

    Publication Year: 1963, Page(s):117 - 122
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (718 KB)

    A crystal valve which is passing current generates both shot and flicker noise, the spectral density of the latter increasing approximately inversely with frequency. Pulse radars are not affected by flicker noise lower in frequency than the pass-band of the i.f. amplifier and are thus subject to only a relatively small degradation in sensitivity. With Doppler radars, however, noise at audio frquen... View full abstract»

  • A u.h.f. technique for producing strong electromagnetic fields of known intensity

    Publication Year: 1963, Page(s):123 - 125
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (313 KB)

    A technique is described for producing strong electromagnetic fields, having a known power density of a few milliwatts per square centimetre, at frequencies of the order of 1 Gc/s. The method has been used to calibrate power-density monitors, with an estimated error limit of ± 1 dB, provided that these instruments can be inserted in the parallel-plate line without a large distortion of the field ...

  • A new treatment of the RC parallel-T network

    Publication Year: 1963, Page(s):126 - 138
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1850 KB)

    The paper shows it to be beneficial to regard the parallel-T as a bridge network and to evaluate its process of convergence to balance. First, new applications result as compared with that which the published literature would indicate is its only manner of use, namely a frequency-sensitive transmission network. Secondly, by considering the parallel-T in the immediate vicinity of its balanced condi... View full abstract»

  • Notes on the use of matrix theory in the analysis of linear feedback circuits

    Publication Year: 1963, Page(s):139 - 148
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (961 KB)

    A set of simultaneous first-order differential equations describing the behaviour of a simple class of linear electrical networks is derived and expressed as a partitioned matrix equation. Some basic relationships of linear feedback theory are then derived in matrix terms. These are: the interpretation of transfer functions in terms of the system characteristic matrix, the relationship between tra... View full abstract»

  • The distortion produced when frequency-modulated signals pass through certain networks

    Publication Year: 1963, Page(s):149 - 156
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (990 KB)

    Frequency-modulated signals are distorted when passed through selective networks, but theoretical attempts to predict the distortion have not been completely successful. The paper presents the results of an experimental investigation carried out to provide accurate measurements of the distortion, against which theoretical predictions can be checked. The networks studied were the parallel resonant ... View full abstract»
