Available in PDF, EPUB and Kindle. Book excerpt: The results of rf breakdown measurements at 106 Mcs in a large waveguide are reported. Breakdown measurements for air, oxygen and nitrogen were made as a function of pressure (10-1000 microns), pulse length and pulse repetition frequency. The data indicate that when diffusion losses are minimized, a value of 30 volts per com-mmHg is obtained for the breakdown threshold over a pressure range from 200 - 1000 microns. The principle that ion cyclotron resonance in weakly ionized gases can be detected, and that the collision cross-section pertinent to the reaction can be determined from the resonance line width is proved. The effect of known processes of electron production and loss upon the steady-state electron concentration and upon atmospheric breakdown is discussed. Breakdown is described as a sudden increase in electron concentration occurring at a specific field, upon negligible increase of field from this value. (Author).

Book Synopsis Radio Wave Propagation by : Chas. R. Burrows
Download or read book Radio Wave Propagation written by Chas. R. Burrows and published by Academic Press. This book was released on 2013-10-22 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio Wave Propagation: Consolidated Summary Technical Report of the Committee on Propagation of the National Defense Research Committee presents all the scientific information and report of experiments. This book discusses the problems encountered in the propagation of radio waves. Organized into three volumes, this book begins with an overview of the technical developments in the study of tropospheric propagation. This text then outlines the general theory of standard and nonstandard propagation together with descriptions and results of transmission experiments designed to test the theory. Other chapters consider the more unusual problems concerning the radar behavior of targets. This book discusses as well the problems of radio wave propagation in the standard atmosphere at frequencies above 30 megacycles. The final chapter deals with the selection and utilization of local terrain features that affect propagation and the performance of equipment. This book is a valuable resource for scientists and engineers in the field of radio wave propagation.

Book Synopsis Radiowave Propagation by : Curt Levis
Download or read book Radiowave Propagation written by Curt Levis and published by John Wiley & Sons. This book was released on 2010-06-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accessible student-oriented approach to radiowave propagation Propagation-the process whereby a signal is conveyed between transmitter and receiver-has a profound influence on communication systems design. Radiowave Propagation provides an overview of the physical mechanisms that govern electromagnetic wave propagation in the Earth's troposphere and ionosphere. Developed in conjunction with a graduate-level wave propagation course at The Ohio State University, this text offers a balance of physical and empirical models to provide basic physical insight as well as practical methods for system design. Beginning with discussions of propagation media properties, plane waves, and antenna and system concepts, successive chapters consider the most important wave propagation mechanisms for frequencies ranging from LF up to the millimeter wave range, including: Direct line-of-sight propagation through the atmosphere Rain attenuation The basic theory of reflection and refraction at material interfaces and in the Earth's atmosphere Reflection, refraction, and diffraction analysis in microwave link design for a specified terrain profile Empirical path loss models for point-to-point ground links Statistical fading models Standard techniques for prediction of ground wave propagation Ionospheric propagation, with emphasis on the skywave mechanism at MF and HF and on ionospheric perturbations for Earth-space links at VHF and higher frequencies A survey of other propagation mechanisms, including tropospheric scatter, meteor scatter, and propagation effects on GPS systems Radiowave Propagation incorporates fundamental materials to help senior undergraduate and graduate engineering students review and strengthen electromagnetic physics skills as well as the most current empirical methods recommended by the International Telecommunication Union. This book can also serve as a valuable teaching and reference text for engineers working with wireless communication, radar, or remote sensing systems.

Available in PDF, EPUB and Kindle. Book excerpt: The physical properties of the ionized layer in the Earth's upper atmosphere enable us to use it to support an increasing range of communications applications. This book presents a modern treatment of the physics and phenomena of the high latitude upper atmosphere and the morphology of radio propagation in the auroral and polar regions. Chapters cover the basics of radio propagation and the use of radio techniques in ionospheric studies. Many investigations of high latitude radio propagation have previously only been published in Conference Proceedings and organizational reports. This book inc.

Download or read book Bibliography on Ionospheric Propagation of Radio Waves written by Wilhelm Nupen and published by . This book was released on 1960 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bibliography comprises a non-exhaustive compilation of over 1400 references to the world's literature in the ionosphere with special emphasis on its effect on reflection, refraction or propagation of electromagnetic waves. The frequencies involved are usually in the low frequency or long wave bands in contrast to those (UHF, VHF and SHF) involved in tropospheric propagation investigations although the pulsed technique at vertical or slant incidence makes use of a wide range of frequencies.

Book Synopsis The D- and E- Regions by : William Swider
Download or read book The D- and E- Regions written by William Swider and published by . This book was released on 1974 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of the E-region is fairly well understood and even many of the dynamical complications of this region have been successfully modeled on individual bases. Some of the major remaining problems of this region are discussed, in particular the nitric oxide concentration, a gas affecting the ratio of the two major E-region ions, O2(+) and NO(+). The D-region is much simpler than the E-region from a dynamical point of view but extremely much more complex from a chemical standpoint. Recent results from a study of the D-region under bombardment by solar protons is emphasized.
