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.
