Shiban Kishen Koul is a professor at the Centre for Applied Research in Electronics at the Indian Institute of Technology Delhi. He is also the chairman of Astra Microwave Products Limited, Hyderabad. He is a Fellow of the Institution of Electrical and Electronics Engineering (IEEE), USA, a Fellow of the Indian National Academy of Engineering (INAE), and a Fellow of the Institution of Electronics and Telecommunication Engineers (IETE). Sukomal Dey is an assistant professor in the Department of Electrical engineering at the Indian Institute of Technology Palakkad. He is a member of the Institution of Electrical and Electronics Engineering (IEEE), USA.

"Koul and Dey are prolific researchers based at the Indian Institute of Technology Delhi (IITD) who have authored hundreds of research articles in this field. Here, they condense decades of their RF switch and phase-shifter work into a densely packed but rewarding volume. But for readers interested in the physics, mechanics, and RF engineering that go into the design and fabrication of micromachined RF switch networks, Koul and Dey provide all the details: design equations; methods of dealing with problems at the micro level, such as stiction; and many measurements of actual constructed systems, including pertinent reliability data. Although RF micromachined switches are still largely in the research phase, the situation may soon change. The book is well-written and rigorous without being obscure and most valuable for emerging specialists in this field."--K. D. Stephan, Texas State University, CHOICE, January 2020 Vol. 57 No. 5Summing Up: Highly recommended. Upper-division undergraduates through faculty and professionals.
