Book Description
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 Description
Terrestrial Propagation of Long Electromagnetic Waves deals with the propagation of long electromagnetic waves confined principally to the shell between the earth and the ionosphere, known as the terrestrial waveguide. The discussion is limited to steady-state solutions in a waveguide that is uniform in the direction of propagation. Wave propagation is characterized almost exclusively by mode theory. The mathematics are developed only for sources at the ground surface or within the waveguide, including artificial sources as well as lightning discharges. This volume is comprised of nine chapters and begins with an introduction to the fundamental concepts of wave propagation in a planar and curved isotropic waveguide. A number of examples are presented to illustrate the effects of an anisotropic ionosphere. The basic equations are summarized and plane-wave reflection from a dielectric interface is considered, along with the superposition of two obliquely incident plane waves. The properties of waveguide boundaries are implicitly represented by Fresnel reflection coefficients. Subsequent chapters focus on boundaries of the terrestrial guide; lightning discharges as a natural source of extremely-low-frequency and very-low-frequency radiation; and the mode theory for waves in an isotropic spherical shell. This book will be a useful resource for students and practitioners of physics.

Book Description
This special issue of Space Science Reviews contains selected papers on electromagnetic man-made and natural environmental interactions. Originally these papers were pre sented at the Fifth International Wrocfaw Symposium on Electromagnetic Compatibility. Wroclaw (Poland), 17-19 September, 1980, a biennial gathering of scientists and engineers. At that time, the symposium organizers selected a few persons of recognized authority and invited them to organize special sessions. Session organizers were given a free hand in the choice of topics and speakers. As a result, several impressive papers originated and a number of interesting people came to Wroclaw to discuss the recent results of their research. Professor Hiroshi Kikuchi from the Nihon University (J apan) was among them, serving as one of the most effective invited session chairmen/organizers at the symposium. The papers presented here were read at Prof. Kikuchi's session. At the symposium they received considerable attention not only because of the fascinating personalities and temperaments of the authors, but mainly because of the timeliness and soundness of their content. Their topic links both scientific and engineering fields in making attempts to resolve these kinds of specific hybrid problems. The problems discussed appear to be of interest not only to the EMC* community but also to a broader forum of persons interested in the areas of electrical and space science, and engineering in general. This opinion was confirmed during the URSI** symposium in Washington, D. C.

Book Description
Electromagnetic Waves, Volume 14: VLF Radio Engineering provides a detailed coverage of the fields involved in very low frequency (VLF) radio engineering. This book serves as a guide for applying the information in the solution of practical problems. Comprised of seven chapters, this volume starts with an overview of the communications aspect following the flow of information carrying energy from the transmitting to receiving locations. This text then presents the complete systems that consider the interrelationship of the various factors. Other chapters explain the basic concept of a VLF antenna, which is a vertical electric monopole over a perfectly conducting flat plane. This book discusses as well the radio wave propagation at VLF, which has been studied theoretically and experimentally for many years. The final chapter deals with the primary components of a complete VLF radio system. This book is a valuable resource for radio engineers, scientists, and researchers.
