About This Book

The text explains the physical principles of wireless transmission and reception, describing electromagnetic oscillations and how waves are radiated and intercepted, then surveys practical apparatus such as aerial systems, transmitters, receivers, coils, condensers, spark gaps and detectors. It treats tuning, coupling and directional methods, discusses telephone transmitters and the wireless telephone, and outlines applications in maritime, military and aerial service. Chapters interweave theory, constructional sketches and illustrations, and conclude with reflections on accomplishments, limitations and the technology's prospective development.
