    The commenter makes two remarks regarding the above-titled paper by P.F. Wilson and M.T. Ma (see ibid., vol.33, p.10-18, Feb. 1991). He notes that the authors' observation that ESD (electrostatic discharge) analysis had mostly focused on currents waveforms, and very little was done concerning the field generated during a discharge, is an understatement. He maintains that whereas the authors are ba... View full abstract»

    The method of moments is used to study the shielding effectiveness of a pigtail-terminated shielded wire (coaxial line) above a perfectly conducting ground plane. Numerical computations are performed in the RF frequency range, i.e. 25-1000 MHz. Pigtail wires on either or both ends of the shield are considered. Results are compared to those from the ungrounded case (floating shield). Results show t... View full abstract»

  • The absorption and coupling of an electromagnetic wave incident on a microstrip circuit with superstrate

    Publication Year: 1992, Page(s):17 - 22
    Cited by:  Papers (10)

    The absorption of an electromagnetic wave incident on a microstrip circuit covered with a dielectric layer is studied. The exact analytical expression for the plane-wave reflection coefficient at the air-superstrate interface of a four-layer model for a superstrate-loaded microstrip circuit is given. Numerical results illustrating the power absorption by the microstrip circuit and the electric and... View full abstract»

  • CW and pulsed mode transfer impedance measurements in coaxial cables

    Publication Year: 1992, Page(s):50 - 57
    Cited by:  Papers (5)

    Transfer impedance measurements have been performed both in frequency and time domains. CW measurements were performed using a matched triaxial system, a quintaxial system, and stripline injection. For nuclear electromagnetic pulse (NEMP) purposes, measurements up to a maximum frequency of 200 MHz are sufficient. For this frequency range the matched triaxial system was found to be the most conveni... View full abstract»

  • Mathieu functions and their applications to scattering by a coated strip

    Publication Year: 1992, Page(s):9 - 16
    Cited by:  Papers (15)

    The elliptic-cylinder harmonics, known as Mathieu (1868) functions, are reviewed. These functions are then used to describe EM scattering by confocal elliptic cylinders where each cylinder's dielectric constant is different. A peculiarity of this problem is that the Mathieu functions in different regions are not orthogonal at regional boundaries. Hence, each boundary couples all harmonics from bot... View full abstract»

  • Shielding effectiveness of conductive polymers

    Publication Year: 1992, Page(s):47 - 50
    Cited by:  Papers (29)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (296 KB)

    The plane wave shielding effectiveness of two new materials, conductive polymers polyacetylene and PBT doped by ion implantation with iodine, is evaluated as a function of frequency, electrical thickness, doping, polarization, and angle of incidence. Conductivity of the polymers, measured in previous investigations by the cavity perturbation technique, is used to compute the overall reflection and... View full abstract»

  • Reflection of VLF radio waves at a junction in the Earth-ionosphere waveguide

    Publication Year: 1992, Page(s):4 - 8
    Cited by:  Papers (4)

    The conditions for the neglect of reflection of VLF modes incident on a junction between the daytime and nighttime Earth-ionosphere waveguides are considered. It is shown that reflections are indeed small but some interesting and possibly significant exceptions may occur at highly oblique incidence. In fact, total reflection may take place for night-to-day transmission at angles within several deg... View full abstract»

  • Analytical treatment of circulant nonuniform multiconductor transmission lines

    Publication Year: 1992, Page(s):28 - 38
    Cited by:  Papers (10)

    The authors analytically study a certain class of nonuniform multiconductor transmission lines (NMTL). This class is described by circulant impedance and admittance matrices. Due to the properties of circulant matrices (which form a special set of normal matrices) it is shown that the NMTL equations can be simultaneously diagonalized with the aid of the position-independent so-called Fourier matri...

  • Modeling common-mode radiation of 3D structures

    Publication Year: 1992, Page(s):57 - 61
    Cited by:  Papers (23)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (404 KB)

    Common-mode radiation, which is often the predominant contributor to the overall radiation from circuit boards and electronic hardware, has in the past been difficult to calculate. Since the return paths for common-mode currents are not obvious, all parasitic circuit elements must be properly taken into account. The authors calculate the radiation, which includes both differential and common-mode ... View full abstract»

  • Electromagnetic coupling to and from shielded cables-optimizing factors

    Publication Year: 1992, Page(s):39 - 46
    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (528 KB)

    Judging the shielding effectiveness of shielded cables often means in practice that only the transfer impedance is considered. The transfer impedance essentially characterizes the coupling via the magnetic field; the coupling via the electric field, the transfer admittance, is mostly neglected. This may be correct for shields with high optical coverage but for optimized single braided shields (cov... View full abstract»

  • A three-loop method for determining the radiation characteristics of an electrically small source

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (248 KB)

    A method for determining the radiation characteristics of an electrically small source is proposed. The source is located at the center of three orthogonal loop antennas, each terminated with identical loads at diametrically opposite points. The electrically small source is represented by equivalent electric and magnetic dipole moments, and these dipole moments can be determined from the appropria... View full abstract»
