Microwave engineering: theory and techniques is a self-sustaining literature for an undergraduate as well as a graduate program on the principles of microwave engineering. The book provides a comprehensive discourse of the fundamentals of the subject and design principles as applied to modern RF and microwave engineering. Starting with the fundamental principles of electromagnetic theory, the book goes on to cover microwave network analysis, impedance matching, directional couplers and hybrids, microwave filters, ferrite devices, noise, nonlinear effects, and the design of microwave oscillators, amplifiers, and mixers. Material on microwave and RF systems includes wireless communication, radar, radiometry, and radiation hazards.
