Physical Principles of Wireless Communications, 2nd Edition

Preface to the First Edition

Wireless communications is based on the launching, propagation, and detection of electromagnetic waves usually at radio or microwave frequencies. It has its roots in the middle of the 19th century when James Clerk Maxwell formulated the basic laws of electromagnetism (viz., Maxwell’s equations) and Heinrich Hertz demonstrated propagation of radio waves across his laboratory. By the start of the 20th century, Guglielmo Marconi had invented the wireless telegraph and sent signals across the Atlantic Ocean using reflection off the ionosphere. Subsequent early embodiments of wireless communication systems included wireless ...
