Book Synopsis Electromagnetic Properties of a Plasma-covered Antenna by : Daniel J. Jacavanco
Download or read book Electromagnetic Properties of a Plasma-covered Antenna written by Daniel J. Jacavanco and published by . This book was released on 1965 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antenna patterns (E-plane) of an X-band horn mounted in a ground plane and covered by a plasma slab were measured. A pulsed plasma was produced by capacitor discharge in a rectangular pyrex container of 6 in. x 2 in. x 24 in. i.d. Microwave interferometer measurements of the electron density were made at 9 and 35 Gc. Antenna patterns are presented which show a sharp decrease in radiated power at certain angles corresponding to the 'optics critical angle'. Good agreement is obtained for the movement of the optics critical angle with plasma density. (Author).

Book Synopsis A Study of Band Edge Distortion in Heavily Doped Germanium by : Freeman D. Shepherd (Jr.)
Download or read book A Study of Band Edge Distortion in Heavily Doped Germanium written by Freeman D. Shepherd (Jr.) and published by . This book was released on 1965 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Details of the energy band structure of degenerate n-type germanium were determined by analysis of fine structure in the 4.2K volt-ampere characteristic of germanium tunnel diodes. No shift in the relative energy of the conduction band minima was observed. The band edge is found to be exponentially distributed with 1/e energies of the order of 10 MeV. There appears to be an ordering mechanism among the group V impurity atoms used as substrate dopants. (Author).
Book Synopsis Experimental Study of Zone Refining of the Binary System Triphenyl Antimony-benzoic Acid by : Marvin S. Brooks
Download or read book Experimental Study of Zone Refining of the Binary System Triphenyl Antimony-benzoic Acid written by Marvin S. Brooks and published by . This book was released on 1965 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study on the zone refining of the binary system triphenyl antimony-benzoic acid is described. The isotope Sb124, which is a strong gamma emitter, was employed as a tracer; this allowed a rapid in situ nondestructive analysis, closely spaced experimental points, and the opportunity to study distribution as a function of varying experimental conditions. With the aid of computers (IBM 7090 and IBM 7044) apparent k's were calculated and the experimental data compared with those predicted from various mathematical models. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The absorption of ozone in the 9.0 micron region of the infrared spectrum, due to transitions from the ground state to the v1 and v3 states, has been studied. This report gives the numerical results of an anlysis of the spectrum including transition frequencies and perturbed intensities ordered by quantum number and by frequency. Calculated and observed special contours are included.
Book Synopsis Effects of Experimental Parameters on Thermoluminescence of a Type II-a Diamond by : Albert D. Johnson
Download or read book Effects of Experimental Parameters on Thermoluminescence of a Type II-a Diamond written by Albert D. Johnson and published by . This book was released on 1965 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermoluminescence provides a method for studying properties of those crystalline imperfections which behave as electron traps and recombination centers in wide bandgap materials. This approach, however, has been used relatively little, possibly due to the fact that the shapes and intensities of thermoluminescent glow curves are functions of several experimental parameters and are often complicated by the overlapping of a number of individual glow peaks. In the present work, experimental parameters were isolated and some of their effects on thermoluminescent glow curves were analyzed. This yielded information on activation energies associated with trapping levels, the nature of the kinetics involved in electron transitions, and electron retrapping. A Type II-a diamond, which has a wide distribution of thermoluminescent glow peaks, was used in this work. (Author).
Book Synopsis An Algorithm for the Deformation Method of Quadratic Programming by : Roger Even Bove

Available in PDF, EPUB and Kindle. Book excerpt: The following paper represents work to date on the deformation method for quadratic programming and thus may be regarded as a sequel to Zahl, S. (1964) A Deformation Method for Quadratic Programming, Research Note AFCRL-63-132. It gives an explanation of a modified Iverson programming language and uses this to give a detailed algorithm for the Zahl Deformation Method of Quadratic Programming.
Book Synopsis Improved Method for Quantum-mechanical Three-body Problems by : Leonard Eyges
Download or read book Improved Method for Quantum-mechanical Three-body Problems written by Leonard Eyges and published by . This book was released on 1965 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quantum-mechanical ground-state problem for three identical particles bound by attractive inter-particle potentials is discussed. For this problem it has previously been shown that it is advantageous to write the wave function in a special functional form, form which an integral equation which is equivalent to the Schrodinger equation was derived. In this paper a new method for solving this equation is presented. The method involves an expansion of a two-body problem with a potential of the same shape as the inter-particle potential in the three-body problem, but of enhanced strength.

Book Synopsis Hydromagnetic Ionizing Waves by : Allen G. Rubin
Download or read book Hydromagnetic Ionizing Waves written by Allen G. Rubin and published by . This book was released on 1965 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory of hydromagnetic ionizing waves has been developed which is valid in the region in which gas pressure is negligible, compared with magnetic pressure. The theory takes into account the energy expended in partial ionization of the gas behind the wave. The usual high conductivity boundary condition behind the wave is not employed. The electric field in front of the wave is taken as a parameter. Results of this theory are compared with available experimental measurements, and show good agreement. (Author).

Book Synopsis The Theoretical and Numerical Determination of the Radar Cross Section of a Finite Cone by : F. V. Schultz
Download or read book The Theoretical and Numerical Determination of the Radar Cross Section of a Finite Cone written by F. V. Schultz and published by . This book was released on 1965 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, rigorous electromagnetic theory is used to determine the nose-on radar cross section of a perfectly conducting cone of finite height. The end cap of the cone is assumed to be a segment of a s spherical surface with center at the apex of the cone. Numerical results have been obtained for a cone having a total apex angle of 30 degrees and for values of [kappa alpha] ranging from 0.0259 to 5.18, where [kappa]=2 [pi]/[lambda] and [alpha] is the radius of the base of the cone. Siegel's Rayleigh method and by using Keller's modified geometrical optics as well as with experimental results obtained by Keys. The comparisons are instructive below [kappa alpha] = 3.2, the apparent upper limit of validity of the present results -- p.[3].
