    Various analog situations in acoustics and electromagnetic waves are described. Certain higher order modes of airborne sound waves in tubes possess a transverse or polarized nature, and electromagnetic properties such as cutoff effects, polarization rotation, and circular polarization can be shown for these sound waves. Externally-guided sound waves, similar to radio waves guided by a dielectric r... View full abstract»

    This paper deals with an interesting type of voltage-controlled negative resistance in heavily doped semiconductor junction diodes. The effect, discovered and explained by Esaki, is due to quantum-mechanical tunneling of carriers through the junction. In the present article, experimental and theoretical results are given which show the diode has great promise for frequencies in the kilomegacycle r... View full abstract»

    The cryosar is a high-speed two-terminal computer component whose operation, at liquid helium temperature (4.2°K), is based on impact ionization of impurities in germanium. Two types of cryosars are discussed: the first, fabricated using uncompensated germanium, exhibits a high resistivity (~107 ohm-cm) until a critical field (~10 volts/cm) is reached, after which the current increases by as much...

  • Parametric Energy Conversion in Distributed Systems

    Traveling wave type parametric amplifiers have been proposed which utilize transmission lines having reactance varied by a propagating wave. An analysis indicates that in systems with little or no dispersion, pumping will not result in exponential gain of an applied signal but in a conversion of energy to a multiplicity of cross-product frequencies. Two physical models of such wide-band systems ar... View full abstract»

  • A Discussion of Sampling Theorems

    The convolution theorem of Fourier analysis is a convenient tool for the derivation of a number of sampling theorems. This approach has been used by several authors to discuss first-order sampling of functions whose spectrum is limited to a region including the origin ("low-pass" functions). The present paper extends this technique to several other cases: second-order sampling of low-pass and band... View full abstract»

    If a random variable can be expressed as a weighted sum of other random variables having known distributions which can be approximated piecewise by, for example, polynomials, the distribution of the random variable can be obtained, relatively easily, by the use of the algorithm described in this paper.

  • An Instantaneous Microwave Polarimeter

    Used as a precision dual balanced mixer with circular waveguide input, the trimode turnstile waveguide junction is the key to a simple microwave polarimeter technique which permits instantaneous viewing of input polarization. Through linear mixing, the relative phase and amplitude of orthogonal components of an arbitrarily polarized input signal are preserved in the IF outputs of the two mixers. A... View full abstract»

    A "Graphical Method" is used for analysis of the magnetization direction in terms of the magnetic energy, and for prediction of the hysteresis loop shape of ferromagnetic thin films. Three major magnetization conditions are discussed: 1) condition of magnetization with an 180° field applied: 2) condition of magnetization with a 90° field applied; and 3) condition of magnetization with both the 9...

  • Analog Computer Measurements on Saturation Currents, Admittances and Transfer Efficiencies of Semiconductor Junction Diodes and Transistors

    Under the usual simplifying conditions, the solution of the diffusion equations at low current densities in junction diodes and transistors is straightforward, if a one-dimensional structure is assumed. In reality, however, such structures are three dimensional, with rotational symmetry round an axis. No useful solutions of such diffusion equations are known for these cases. An analog computer was... View full abstract»
