    A new model is presented for the accurate prediction of transfer impedances of braided coaxial cables. This model is compared with earlier models proposed by E. F. Vance (1972, 1975) and M. Tyni (1975). A large number of measurements were carried out on several braided cable samples, and the accuracy of the new model is evaluated using transfer impedance values obtained from these measurements View full abstract»

  • A critical assessment of the US code for lightning protection of boats

    Publication Year: 1991, Page(s):132 - 138

    It is argued that the US code for lightning protection of boats is seriously inadequate. Downconductor conductance should be specified as that of #4 gauge copper rather than the #8 gauge presently specified in order to minimize the risk of overheating and melting. The 1-ft2 ground plate is shown to be inadequate to prevent side flashes in fresh water. The magnitude of the potential gra... View full abstract»

    The susceptibility of commercial aircraft to the SEMP (simulated electromagnetic pulse) hazard is evaluated on the basis of the US Army's AESOP (Army EMP simulator operations) simulator. The following issues are addressed: the AESOP environment at various altitudes, coupling to cables within commercial aircraft, known transient safe levels for commercial aircraft, and determination of threshold le...

  • Power-mains transients from connection of resistive loads and a possible capacitive mitigation

    Publication Year: 1991, Page(s):113 - 119
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (576 KB)

    The voltage transient disturbances produced in power mains by the connection of resistive loads are analyzed theoretically and experimentally. The effect of a series inductance is included in the circuit model. A fast unidirectional (exponential) waveshape that reduces the instantaneous phase-to-neutral voltage is demonstrated. Differential- and common-mode components are separated, and the basic ... View full abstract»

    The initial development of the balanced transmission-line wave sensor is described. This sensor is being developed to address the need for a directional sensor when dealing with extrapolation issues for hybrid electromagnetic pulse (EMP) simulators. A prototype sensor was designed and tested. It provided good performance with measured front/back ratios between 20 and 29 dB. This may be adequate fo... View full abstract»

  • Analysis of single-tone spurious effects in nondesensitized radio communication systems

    Publication Year: 1991, Page(s):77 - 89
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (1040 KB)

    An investigation and analysis of STS (single-tone spurious) interferences are presented. The analysis provides a new semiempirical computational method of obtaining a list of forbidden, potentially disturbing STS frequencies for each nonsensitized receiver operating channel. A newly developed UHF/FM or FSK modulated radio communication system using two frequency converter stages is used as an exam... View full abstract»

  • Remark on Harmuth's `Correction of Maxwell's equations for signals. I' [and response]

    The commenter maintains that the claims made by H.F. Harmuth in the above-titled paper (ibid., vol.EMC-28, p.250-8, Nov. 1986) that a satisfactory condition for the existence of solutions for transients in lossy media is the modification of Maxwell's equations by the addition of a magnetic current density is not valid. In his reply, Harmuth states that if the commenter's claim holds true regardles... View full abstract»

  • On the direct calculation of a transient plane wave reflected from a finitely conducting half space

    Publication Year: 1991, Page(s):90 - 96

    An approach to the computation of the electromagnetic field reflected from a lossy half-space directly in the time domain is discussed. This approach requires first evaluating the impulse response of the half-space and then convolving it with the specified incident field waveform. To obtain the impulsive reflected field, either for vertical or horizontal polarization, approximations to the Fresnel... View full abstract»

  • A note on the cutoff frequency of TE01 mode in TEM cells

    Publication Year: 1991, Page(s):145 - 146

    It is shown that due to the similarity of the structures of the TEM cell and the finned waveguide, the closed-form expression for the cutoff frequency of the TE10 mode in the finned waveguides can be used to calculate the cutoff frequency of the TE01 mode in the symmetric TEM cells. The results obtained by the expression given agree with various numerical methods to within 1%... View full abstract»

  • Currents and fields of thin circular and elliptical loops

    Approximate solutions for the current of thin circular and elliptical loops have been determined on the basis of an asymptotic antenna theory. The fields at and around the center have been calculated to illustrate the broadband behavior of these structures when used as electromagnetic pulse (EMP) simulators. Fields calculated with this approach and those measured in an actual EMP simulator are com... View full abstract»
