    Detailing the active and passive aspects of microwaves, Microwave Engineering: Concepts and Fundamentals covers everything from wave propagation to reflection and refraction, guided waves, and transmission lines, providing a comprehensive understanding of the underlying principles at the core of microwave engineering. This encyclopedic text not only encompasses nearly all facets of microwave engineering, but also gives all topics—including microwave generation, measurement, and processing—equal emphasis. Packed with illustrations to aid in comprehension, the book:

    • Describes the mathematical theory of waveguides and ferrite devices, devoting an entire chapter to the Smith chart and its applications
    • Discusses different types of microwave components, antennas, tubes, transistors, diodes, and parametric devices
    • Examines various attributes of cavity resonators, semiconductor and RF/microwave devices, and microwave integrated circuits
    • Addresses scattering parameters and their properties, as well as planar structures including striplines and microstrips
    • Considers the limitations of conventional tubes, behavior of charged particles in different fields, and the concept of velocity modulation

    Based on the author’s own class notes, Microwave Engineering: Concepts and Fundamentals consists of 16 chapters featuring homework problems, references, and numerical examples. PowerPoint® slides and MATLAB®-based solutions are available with qualifying course adoption.

Possessing over 40 years of teaching experience, the former AMU University Medal recipient, professor, and chairman of the AMU Department of Electronics Engineering is an IETE India fellow, IEI member, and SSI and ISTE life member. A popular invited lecturer, he has published 23 journal and conference papers, co-authored the book Antennas and Wave Propagation (Special Indian Edition), edited the book A Guide to the Laboratory Practice in Electronics and Communication Engineering, and received the Pandit Madan Mohan Malviya Memorial Gold Medal from JIE India.

    "The book demonstrates a good understanding of the author’s knowledge of microwave engineering. It has extensive practical applications and a wide variety of problems with worked solutions. The book is written in such a way that the reader, through personal study, could achieve a satisfactory education in the subject of microwave engineering."
    —Brian Klaveness, Principal Lecturer and Programme Leader at Glyndwr University, Wrexham, UK

    "... covers everything from wave propagation to reflection and refraction, guided waves, and transmission lines, giving all topics equal emphasis and providing a comprehensive understanding of the underlying principles at the core of microwave engineering. In my opinion, the book is well written and easy to follow, so I am highly recommending it as a textbook for electronics and communication engineering students at the undergraduate level, though it may serve as a solid basis for advanced courses on microwaves at the postgraduate level as well."
