  • Calculation of Near Field of Circular Aperture Antenna Using Geometrical Theory of Diffraction

    Publication Year: 1971, Page(s):29 - 34
    Cited by:  Papers (3)

    A tutorial account of the geometrical theory of diffraction is presented, and as an application of the theory the near field of a circular aperture antenna is calculated. This method is useful in calculating quite accurately the field in regions far from the antenna axis. The method finds appeal in its simple mathematical formulation which lends itself to obtaining numerical results with relative ... View full abstract»

    The asymmetry in current density along the periphery of cylindrical scattering obstacles of both finite and infinite length illuminated by a plane wave electromagnetic field is discussed. In the Appendix the same problem for a spherical scatterer is considered. View full abstract»

  • Transient Currents Induced on a Metallic Body of Revolution by an Electromagnetic Pulse

    A numerical technique is presented that may be used to predict the current induced on a thin metallic body of revolution excited by an electromagnetic pulse. Examples are given. Introduced here is the use of the radiation condition in a finite difference solution. This development alleviates the requirement that finite difference techniques be applied to a bounded region of space. View full abstract»

  • Interaction of Magnetic Fields and Ferromagnetic Shields

    An analytic procedure is developed for the purpose of determining the effectiveness of ferromagnetic shields in shielding against magnetic fields. The basic approach is to separate the magnetization relation of a ferromagnetic material into regions in which each region is characterized by a constant permeability. Maxwell's equations are then solved in each time-varying geometric region (which corr... View full abstract»

  • Pseudorandom Coding for Improved Antenna Range Measurements

    Publication Year: 1971, Page(s):51 - 56

    The autocorrelation function for pseudorandom binary codes is such that these codes are ideal for suppressing unwanted reflections on antenna ranges. The method presented here depends on amplitude modulating the transmitted signal with a maximum-length linear recurring modulo-two sequence (PN code) and correlating it at the receiver with a delayed version of the code. In this way reflections whose... View full abstract»

  • Prediction of Mixer Intermodulation Levels as Function of Local Oscillator Power

    During intermodulation testing with diode mixers an increase of intermodulation interference was observed due to an increase of LO power incident to the mixer. This phenomenon conflicted with the theory that increase of LO power reduces intermodulation output of the diode mixer. In these tests the intermodulation decreased as expected when the LO power was further increased. Results of a theoretic... View full abstract»

  • A Spectrum Prediction Technique for AM Pulses of Arbitrary Shape

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3699 KB)

    The accuracy of predicting spectra for pulsed AM systems is greatly improved by merely describing the time-domain signal with more accuracy. Specifically, a series of straight lines is used to approximate an arbitrary signal shape. Experimentally, a pulse-shaping network and spectrum analyzer were used to generate and record various time- and frequency-domain shapes. These results were compared to... View full abstract»

  • Multiple and Partial Correlation between Atmospheric Noise Levels at Different Frequencies

    Publication Year: 1971, Page(s):69 - 70

    Multiple and partial correlations between atmospheric noise levels at 105 kHz, 280 kHz, 1.6 MHz, and 2.9 MHz were examined. These provide a quantitative measure for the improvement in predicting the noise level at one frequency from the noise levels at a number of other frequencies rather than from that at just one frequency. The analysis also leads to the interesting result that atmospheric noise... View full abstract»

  • Measurement of Rocket Engine Spark Gap Ignition EMC

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2263 KB)

    A spark may be used to ignite nonhypergolic rocket engine propellants. Broad-band radiated interference from the spark plug will be radiated through the thrust chamber throat and will limit the level to which interference can be reduced. Tests have been performed by Textron's Bell Aerospace Company to determine the extent to which the rocket engine thrust chamber attenuates radiated interference f... View full abstract»
