Book Zonal Harmonics in Low Frequency Terrestrial Radio Wave Propagation  Classic Reprint

Download or read book Zonal Harmonics in Low Frequency Terrestrial Radio Wave Propagation Classic Reprint written by J. Ralph Johler and published by Forgotten Books. This book was released on 2017-10-27 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Zonal Harmonics in Low Frequency Terrestrial Radio Wave Propagation An improved definition of the reflection coefficient matrix is presented which accounts for the reflection process in a manner which can be justified both mathematically and physically. In fact, the entire reflection coefficient matrix for the anisotropic ionosphere can be retained as a variable of the zonal harmonic summation process with resultant improvement in computation accuracy. Demonstrative compu tations indicate considerable advantage in the method as an alternate approach to the propagation problem. Key Words: Extra low frequencies, geometric -optics, geometric series, lf, vlf, elf mode theory, low frequencies.

Book Propagation of Radio Waves at Frequencies below 300 Kc s

Download or read book Propagation of Radio Waves at Frequencies below 300 Kc s written by W. T. Blackband and published by Elsevier. This book was released on 2014-06-28 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Propagation of Radio Waves at Frequencies Below 300 KC/S covers the proceedings of the Seventh Meeting at the AGARD Ionospheric Research Committee, held in Munich, Germany on September 17-21, 1962. This book is organized into eight parts encompassing 32 chapters. The first parts deal with research studies concerning the electron density distribution and some properties of the lower ionosphere, as well as the effect of D-layer irregularities on radio wave propagation. The next parts explore the low frequency propagation in the lower ionosphere, the measurement of oblique incidence, and the statistical frequency spectrum of radio noise below 300 kc/s. The remaining chapters discuss the diurnal changes, the statistical prediction, the mode theory, and the propagation of very and extremely low frequency radio waves in the ionosphere. These chapters also examine the Earth resonance. This book will prove useful to astronomers, astrophysicists, and space scientists.

Book Theoretical LF  VLF Field Calculations with Spherical Wave Functions of Integer Order

Download or read book Theoretical LF VLF Field Calculations with Spherical Wave Functions of Integer Order written by J. Ralph Johler and published by . This book was released on 1970 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The propagation of LF and VLF terrestrial radio waves is simulated on the computer with a precise theory of spherical wave functions of integer order. Anisotropic reflections from an electron and ion density profile of the ionosphere are accommodated by the analysis. Variations in the profile and the magnetic field with distance along the propagation path can be introduced ad hoc. The analysis method is incorporated into a computer program which is written in a flexible manner so that it can be applied to a variety of scientific studies of low-frequency ionospheric wave propagation. Calculations of current interest are presented to illustrate use of the technique. Amplitude perturbations of approximately 15 decibels are described at 60 kHz as a result of an electron density profile perturbation. It is also found that the 26 kHz signal is comparatively insensitive to a variation in magnetic dip angle when propagation occurs in the daytime near the magnetic equator. Thus, using values of the magnetic field vector at the center of the propagation path is a good approximation in certain circumstances.

Book Electromagnetic Waves in Stratified Media

Download or read book Electromagnetic Waves in Stratified Media written by James R. Wait and published by Elsevier. This book was released on 2013-10-22 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Series of Monographs in Electromagnetic Waves, Volume 3: Electromagnetic Waves in Stratified Media provides information pertinent to the electromagnetic waves in media whose properties differ in one particular direction. This book discusses the important feature of the waves that enables communications at global distances. Organized into 13 chapters, this volume begins with an overview of the general analysis for the electromagnetic response of a plane stratified medium comprising of any number of parallel homogeneous layers. This text then explains the reflection of electromagnetic waves from planar stratified media. Other chapters consider the oblique reflection of plane electromagnetic waves from a continuously stratified medium. This book discusses as well the fundamental theory of wave propagation around a sphere. The final chapter deals with the theory of propagation in a spherically stratified medium. This book is a valuable resource for electrical engineers, scientists, and research workers.
