    Experience in selecting students for admission to undergraduate engineering colleges provides a clear outline for a program of tests and related procedures that should prove helpful in identifying potential engineering talent early in high school. Qualified students may then be guided toward adequate preparation for engineering training. Such a program would include the following as a basic minimu... View full abstract»

  • Fundamentals of Secondary Electron Emission

    Publication Year: 1951, Page(s):1367 - 1373
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1707 KB)

    Secondary electron emission is of great importance to the physicist because of its bearing upon the problem of the interactions between fundamental particles and to the radio engineer because of its applications, as well as its effect, upon the operation of electronic tubes. A complete theoretical picture capable of accounting quantitatively for all observed phenomena does not exist. Secondary ele... View full abstract»

    Extended measurements are reported which indicate the existence of pronounced nocturnal superrefraction during an appreciable percentage of the summer and of very persistent scattering by atmospheric turbulence near the surface in all seasons. The measurements were taken over rolling midwestern terrain at a distance of about 100 miles. Mobile road tests were made to supplement the fixed-point meas... View full abstract»

    This paper presents a procedure for measuring the dielectric properties of metal-loaded artificial dielectrics in the microwave region by the use of the short-circuited line method. Formulas, based on transmission-line theory, are included and serve as guides in predicting the approximate dielectric properties of certain loading configurations. View full abstract»

    The impedance of a two-terminal network is defined completely by the insertion loss and phase shift it produces when inserted between known sending and receiving impedances. Recent advances in precise wide-band phase and transmission measuring circuits have permitted practical use of this principle. Reactive and resistive impedance components are read directly from a simple graphical chart in whic... View full abstract»

    Speech-reinforcement systems in six large auditoriums were evaluated, using subjective rating tests, word-articulation tests, and, in two cases, a new test method. This method, called the "terminal-word test," makes possible the quantitative measurement of speech intelligibility for a sound system in actual use. A graphical method is presented for calculating the performance of a sound system in w... View full abstract»

    A general formula for the radiation resistance of a two-wire line is derived by means of a Poynting vector integration over a large sphere. The result is shown to be in agreement with that computed by other techniques. Formulas for the useful special cases of a lossless system and a nonresonant line are presented. View full abstract»

    A storage system which will store binary (on or off) pulses has been constructed, and should prove useful in laboratory studies of certain communication problems. The system comprises two storage channels, each utilizing an MIT electrostatic storage tube and switching circuits which route incoming pulses into one channel while stored pulses are being recovered from the other. Pulses are stored in ... View full abstract»

    In this paper it is shown how the electric and magnetic polarizabilities of an aperture may be determined accurately by electrolytic-analog measurements. Measured magnetic-polarizability data are given for rectangular-, rounded-slot-, cross-, rosette-, dumbbell-, and H-shaped apertures. View full abstract»

    The ancient idea of a combination coarse and fine adjustment is shown to be applicable to the design of precision automatic control systems. In the particular class of systems discussed, the coarse adjustment is taken to be a separate element operated by the input, but outside the feedback loop. Its position outside the feedback loop qualifies the coarse controller as an open-cycle system, and mak... View full abstract»

    A method of analyzing the response of automatic frequency-control systems, operating in conjunction with a narrow band-pass filter, is presented in this paper. A time-lag, equivalent to the reciprocal of the bandwidth, is assigned to the filter. Circuit parameters are established for operation near the critically damped response condition. The equations of the system are derived with the aid of th... View full abstract»

  • The Folded Fan as a Broad-Band Antenna

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3552 KB)

    High-frequency model studies are reported which promise an antenna which operates over a 4-to-1 frequency range with a maximum power loss, due to mismatch, of 18.5 per cent. In the projected naval application, this loss is not unusual with currently used antenna systems. The antenna consists of an ordinary fan-type antenna folded back to ground, that is, electrically connected at the top to an ide... View full abstract»

    This paper describes a method for eliminating the feed-cable effect in the measurement of aircraft wing-cap and tail-cap antenna impedances with the aid of models. The procedure employed allows greater accuracy in measurement than that obtainable with conventional techniques, but its application is restricted to use use on simplified models. The advantages and limitations of the method are discuss... View full abstract»

    A simple method of "tuning up" a multiple-resonant-circuit filter quickly and exactly is demonstrated. The method may be summarized as follows: Very loosely couple a detector to the first resonator of the filter; then, proceeding in consecutive order, tune all odd-numbered resonators for maximum detector output, and all even-numbered resonators for minimum detector output (always making sure that ...

    Energy from a remote transmitter excites a receiving antenna that is erected vertically over a large conducting plane and base-loaded by a vertical slotted coaxial cavity of variable length. From measurements of the location and half-power width of resonance curves, the combined phase and damping factors for the two ends of the cavity are determined. By measuring these factors for the lower end of... View full abstract»
