    Attenuation measurements were made in the 1 to 1000 MHz frequency range in two wet-granite tunnels leading to an underground facility. The purpose of the measurements was to determine the vulnerability of the facility to interfering electromagnetic radiation. Continuous-wave signals were propagated within the tunnels and the signal levels at various distances from the transmitter were measured wit... View full abstract»

    The use of the linear antenna as a probe to measure both the constitutive parameters of material media and the electric field interior to such media is reviewed. The advantages of using probes with a particular geometry (i. e., electricaUy short, resonant, bare or insulated) for specific applications are discussed. Applications in the areas of geophysics and biophysics are cited. View full abstract»

    Light transmittance and the Rf shielding effectiveness of a gold film on a glass substrate is investigated. The dependence of the transmittance of visible light upon the thickness or surface resistance of a gold film on a glass substrate is determined numerically by the optical properties of the gold film and glass substrate. The Rf shielding effectiveness produced in the far field over the freque... View full abstract»

    This work discusses the active circuit behavior of typical bipolar transistors as they are injected with low level microwave energy. The observed response is found to be due to square law rectification of the energy at the transistor's emitter-base junction. A rectification efficiency measurement'is described which gives a quantitative measure of a transistors sensitivity to microwave interference... View full abstract»

    The electromagnetic susceptibility of UHF transistors is investigated. The 2N5179 RF amplifier type transistor was selected as a representative UHF transistor because of its chip structure. It is a silicon n-p-n epitaxial planar transistor with an interdigitated baseemitter metallization pattern. Several manufacturer's versions were tested. A single RF pulse at 240 MHz was applied directly to the ... View full abstract»

    The Applications Technology Statellite-6 (ATS-6) has successfully withstood repeated entrances into and exits from occult in a period centered on the 1974 autumn equinox, during which it was subject to potential changes as hikh as 11 000 volts based on onboard measurements. Much of the outer surface of the spacecraft is an insulator, dictated by thermal control design. Consequently, special measur... View full abstract»

  • The Effect of Cylindrical Ferromagnetic Shells on the Self and Mutual Inductance of Parallel Wires

    Publication Year: 1975, Page(s):234 - 237

    The effect of ferromagnetic shields on the self and mutual inductances of the wires enclosed by a ferromagnetic shell has been theoretically analyzed. Some theoretical equations based on a simplified model, which assumes that the driving wires and returning wires are located within two separated magnetic shells, are derived. The analysis shows that the effect of the ferromagnetic shells on the ind... View full abstract»

    The method of moments is applied to the computation of the charge distributions and capacitance matrix for electrostatic systems of bare and dielectric-coated cylindrical wires. Several choices of expansion functions are investigated in detail and compared. Harmonic series expansion functions are shown to be especially well suited to problems involving systems of closely-spaced dielectric-coated c... View full abstract»

    An automated model that calculates the frequency separation requirements for interference free operation of electronic systems located in a given environment is described. Using these frequency separation requirements, the model assigns a channel to each system in the environment based on the frequencies available to each. The model calculates inter system, antenna coupled interference levels only... View full abstract»

    The currents and charges induced in a pair of electrically thin crossed wires by a normally incident plane electromagnetic wave are derived by analytical methods. The boundary conditions at the ends and at the junction are explained. The solution of a new integro-differential equation for the currents is obtained in terms of trigonometric and integral-trigonometric functions. Depending on the elec... View full abstract»

  • Walsh-to-Fourier Spectral Conversion for Periodic Waves

    Relations are developed for the determination of the Fourier spectra of frequency-limited periodic waves from truncated Walsh spectra. The matrix conversion process is simplest if the highest-order Walsh coefficient in the spectru to be converted is 2n, where n is an integer. For such cases, compensation for truncation consists of a diagonal matrix that premultiplies the Walsh to Fourier conversio... View full abstract»
