    A unified treatment of matrix methods useful for field problems is given. The basic mathematical concept is the method of moments, by which the functional equations of field theory are reduced to matrix equations. Several examples of engineering interest are included to illustrate the procedure. The problem of radiation and scattering by wire objects of arbitrary shape is treated in detail, and il...

    Digital filtering is the process of spectrum shaping using digital components as the basic elements. Increasing speed and decreasing size and cost of digital components make it likely that digital filtering, already used extensively in the computer simulation of analog filters, will perform, in real-time devices, the functions which are now performed almost exclusively by analog components. In thi... View full abstract»

    This paper discusses the operation of a new superconductive logic element. In geometry, the element resembles the in-line cryotron and like the in-line cryotron exhibits gains of greater than unity when biased. The gate, however, is a Josephson junction. The two states, zero-voltage and "resistive," of the junaction are both superconducting states, one being a pair tunneling state, the other a sin... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (428 KB)

    Analysis of the signal-to-noise ratio of optical point detectors under conditions of large background radiation (BLIP detection) gives relations describing the background limit to the sensitivity of point-to-point optical communication systems. In narrowband applications, noise-equivalent-power (NEP) has a utility for study of the point BLIP detector which is equivalent to that of the detectivity ... View full abstract»

  • Room temperature instabilities in MOS structures with pyrolytic SiO2films

    Publication Year: 1967, Page(s): 214
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (129 KB)

    Instabilities at room temperatures in MOS structures having SiO2films deposited by decomposition of TEOS are manifested in a shift, along the voltage axis, of the capacitance-voltage characteristics after voltage stress in the reverse direction. Typical shifts amounted to 13 volts and could not be reversed by a forward voltage. View full abstract»

  • Plane wave diffraction from a small half-sphere mounted on a large conducting body

    Publication Year: 1967, Page(s):214 - 216
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (319 KB)

    Using image theory and the scattering solution for a sphere, the plane wave scattering by a small, perfectly conducting half-sphere on a conducting plane is obtained first. The scattered field can then be identified as that radiated from a combination of electric and magnetic dipoles on the plane. Equating these dipole fields to the corresponding radiation dipoles, we can solve for the induced sca... View full abstract»

    A circuit is described in which avalanche transistors in parallel generate high-current, fast ristime pulses suitable for driving injection lasers. A 55 A, 20 ns risetime pulse was produced at a repetition rate of 10 kHz. An adjustable biasing technique makes possible the simultaneous avalanche of unmatched transistors. View full abstract»

    A thorough investigation is made of the properties of dual input null networks which are known to have the distinctive feature of single-element control of the notch frequency. The results show the principal advantages and limitations of such networks and also the relative merits and demerits of the parallel- T and bridged- T types. View full abstract»

    Attention is called to an important but little-known paper by Mortley which anticipates by at least a decade the Shockley concept of energy-trapping in thickness-shear piezoelectric vibrators such as AT-cut quartz plates. Some extensions of the Mortley theory are also presented. View full abstract»

    Recent results with germanium IMPATT diode oscillators are reported. Both n-p-i-p+and n-p structures have shown noise figures of 30 ± 1 dB when operated as amplifiers under high gain conditions in the 8 to 10 GHz range. This represents an approximate 10-dB improvement over comparable Si devices. Power outputs of 30 mW at 3 percent efficiency and 250 mW at 6 percent efficiency were ... View full abstract»

    A report is given on the construction and testing of a traveling-wave electrooptic modulator that requires a nominal 5-watt drive power to obtain 30 percent amplitude modulation from 0 to 3-GHz. The modulator employs potassium-dihydrogen-arsenate crystals and has been tested at 6328 Å with CW drive power. View full abstract»

  • On ladder networks and continued fractions

    Driving-point immittance of general ladder network can always be put in the form of a continued-fraction expansion, where all the quotient terms are positive-real functions. Recursion formulas for transmission (ABCD) parameters lead us to another form of continued fraction. These fractions, whose terms are not (in general) positive-real functions, are chained by means of negative signs. It is not ... View full abstract»

    Stochastic approximation algorithms are used to construct least squares error approximations to density and distribution functions. The approximation is linear in terms of the parameters to be estimated. The only information available to the algorithm is a sequence of independent samples from the distribution of density being approximated. View full abstract»
