    The electromagnetic interference (EMI) from various forms of electrical discharges was investigated, and the measured levels were compared with civilian and military statutory limits of interference. The more stable arc forms, such as moderate-current (50-250A) arcs in argon flow, gave low levels of EMI conforming with all statutory limits throughout the frequency spectrum (0.1-1000 MHz). The inte... View full abstract»

    Atmospheric noise data collected by the ARN-2 recorder at Delhi were examined to study the effect of sunspot number (SSN) on the year-to-year variations in the noise levels during 1600-2000 h. Since ionospheric propagation characteristics and thunderstorm activity undergo systematic hour-to-hour changes during this time period, the data were analysed on an hourly basis. The burst-noise-level data ... View full abstract»

    The objective of the work described in this paper is to make a comparison of various suppression circuits, connected across the relay, for reducing electromagnetic interference, considering also the effect of relay armature release time (dropout delay time). Tested suppression circuits described in this paper are diode, diode with Zener diode (two cases with different Zener voltages), diode with r... View full abstract»

  • Multiple-Pin Connector with Internal Surge Protection

    Publication Year: 1978, Page(s):211 - 215
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1536 KB)

    The design and performance characteristics of a multiplepin electronic surge arrestor (Bulk ESA) are described. This device is a simple, compact unit providing electromagnetic pulse (EMP) and lightning protection of systems in which many signal lines enter sensitive electronic equipment. Basically since it takes one device to protect each wire entering a system, the efficient packaging of the Bulk... View full abstract»

  • Solution of the Transmission-Line Equations for Three-Conductor Lines in Homogeneous Media

    Publication Year: 1978, Page(s):216 - 222

    Formulas are obtained for the terminal voltages of a transmission line consisting of three conductors immersed in a homogeneous medium. No simultaneous equations need be solved and the result does not require that the line be electrically short. Typical applications are lines composed of three wires, two wires above a ground plane, and two wires within a cylindrical shield. Certain interesting pro... View full abstract»

  • Random Effects in Planar Arrays of Thin-Wire Dipoles

    The effects of random errors in the voltage excitation of a planar array of thin-wire dipoles are analyzed. Mutuals are taken fully into account. The method of moments is applied iteratively in conjunction with a random-sampling process, to obtain mean far-field beam patterns and their expected variation, as well as several "expected-gain" quantities. Sinusoidal expansion and weighting functions a... View full abstract»

  • Frequency-Sharing and Spread-Spectrum Transmission with Large Relative Bandwidth

    Publication Year: 1978, Page(s):232 - 239
    Cited by:  Papers (9)  |  Patents (18)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1663 KB)

    Radio transmission has been based traditionally on the concept of a small relative frequency bandwidth, which permits the use of circuits and structures that resonate with sinusoidal functions. This approach created no problems until high-resolution radar advanced to pulse durations in the order of 1 ns, and spread-spectrum transmission to frequency bands in the order of 100 MHz. The use of a smal... View full abstract»

  • On the Electromagnetic Fields from a Hybrid Type of EMP Simulator

    Publication Year: 1978, Page(s):240 - 247
    Cited by:  Papers (1)

    A typical hybrid type of EMP simulator that is used in the simulation of the nuclear electromagnetic pulse is analyzed. Because of the width of the pulse frequency spectrum, the behavior of the antenna is determined separately for three specific frequency regimes. Also, the pulse-power source interaction with the antenna is considered. After the frequency response of the antenna is determined, Lap... View full abstract»

  • Microwave Radiation-Pattern Measurements in the Presence of Biological Specimens

    Publication Year: 1978, Page(s):248 - 258
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4018 KB)

    Power density is used extensively as an index of hazard to living systems from microwave radiation. To assess this, the biological effect observed in test specimens is related to power density, as measured in the absence of the specimen. The usefulness of power density as a biologically meaningful parameter has often been questioned and other alternatives have been proposed. In this paper, the aut... View full abstract»

    Techniques for the computation of near fields of thinwire antennas have been reported in the past. In this paper, the methods for such computation are reviewed, some recent developments are described, and extensive experimental verification is reported. The computed near fields of resonant dipole are compared with experiment. The near fields of broadside and endfire linear arrays are reported. The... View full abstract»

  • Reference Potential Terms in Static Capacitance Calculations Via the Method of Moments

    In an earlier publication [1], a numerical method for determining the per-unit-length generalized capacitance matrix for a system of parallel cylindrical conductors with cylindrical dielectric insulations (wires) was given. In the formulation of the method, potential expressions were developed in which reference-potential terms were omitted. In this paper, a proof of the validity of omitting the r...
