The ridge waveguide, which is a rectangular waveguide with one or more metal inserts (ridges), is an important transmission line in microwave engineering, now widely used in commercial electronics and communications devices. This book gives the reader direct access to this subject without need for exhaustive search of research papers.

Professor Joseph Helszajn OBE is an international authority on nonreciprocal microwave circuits and devices. After industrial experience in the USA he obtained his Ph.D. from the University of Leeds and spent much of his academic career at Heriot-Watt University, where he founded its microwave laboratory. A Fellow of the IEE and IEEE, he acted as an Honorary Editor of the IEE Proceedings for 18 years and has published 11 books. In 1995 he was awarded the IEE JJ Thomson Medal.
