A concise introduction to waveguides, Microwave and Optical Waveguides presents the fundamental mathematical and physical principles that underpin the operation of waveguides. The book provides a unified treatment of various waveguides, as used in different wavelength regions throughout the spectrum. It emphasizes the features common to each type without over-emphasizing their differences. Each chapter examines different types of waveguides, from the most simple (transmission lines) to circular dielectric waveguides. Chapters also include detailed examples and a set of problems. The book contains references for further reading. Assuming background knowledge of basic electromagnetic theory as well as some mathematical fundamentals, Microwave and Optical Waveguides ensures that both students and engineers become familiar with the important concepts and techniques irrespective of the frequency band or terminology used for a particular waveguide.
