Our aim in this book is to present a bird’s-eye view of microwave tubes (MWTs) which continue to be important despite competitive incursions from solid-state devices (SSDs). We have presented a broad and introductory survey which we hope the readers would be encouraged to read rather than going through lengthier books, and subsequently explore the field of MWTs further in selected areas of relevance to their respective interests. We hope that the present book would motivate newcomers to pursue research in MWTs and apprise them as well as decision makers of the salient features and prospects of as well as the trends of progress in MWTs. The scope of ever expanding applications of MWTs in the high power and high frequency regime will sustain and intensify the research and development in MWTs in coming years.

About the Authors:

Vishal Kesari received an MSc (Physics) degree from Purvanchal University, India, and a PhD (Electronics Engineering) degree from the Institute of Technology, Banaras Hindu University (IT-BHU) (now known as IIT-BHU), India, in 2001 and 2006, respectively. He has worked as a Research Fellow at the Centre of Advanced Study, Electronics Engineering Department, IT BHU, and significantly contributed to sponsored research projects at the Centre of Research in Microwave Tubes, IT-BHU. He served as a lecturer at the Birla Institute of Technology, Ranchi, India, and the Indian Institute of Information Technology, Allahabad, India, before joining as a scientist at the Microwave Tube Research and Development Centre, Defence Research and Development Organisation, Bengaluru, India. His research interests include microwave and millimeter-wave vacuum electronic devices. He has authored two books: (i) Analysis of Disc-loaded Circular Waveguides for Wideband Gyro-TWTs (Lambert Academic Publishing AG & Co., Germany, 2009), and (ii) High Power Microwave Tubes: Basics and Trends (IOP Concise Physics; Morgan & Claypool Publishers, London, 2018) (with B N Basu as the co-author), and numerous research papers in peer-reviewed journals and conference proceedings. He has, to his credit, a number of international and departmental level awards including the DRDO Young Scientist Award, 2012. He has acted as a reviewer for various peer-reviewed journals and conference proceedings. He is a life member of the Vacuum Electronic Devices and Application Society, India.

B.N. Basu received B.Tech, M.Tech and PhD degrees from the Institute of Radiophysics and Electronics, Calcutta University in 1965, 1966 and 1976, respectively. He served several organizations in India: RIT, Jamshedpur; CSIR-CEERI, Pilani; DRDO-DLRL, Hyderabad; IT-BHU, Varanasi; IFTM University, Moradabad; and SKFGI, Mankundu. He took visiting assignments abroad at Lancaster University, UK; Seoul National University, Korea; and KIT, Karlsruhe, Germany. He was the CSIR Distinguished Visiting Scientist at CSIR-CEERI, Pilani, and Consultant at DRDO-MTRDC, Bengaluru. He played a pivotal role in establishing MOUs (i) between the Department of Electronics Engineering, BHU and CSIR-CEERI, Pilani; (ii) between Seoul National University and CSIR-CEERI, Pilani; and (iii) between SKFGI, Mankundu and CSIR-CEERI, Pilani. He was President of the Vacuum Electron Devices and Application Society, Bengaluru. He has authored (or co-authored) more than a hundred research papers in journals of international repute (including 37 in IEEE Transactions) and six monograph chapters in the area of microwave tubes. He has authored four books: (i) Electromagnetic Theory and Applications in Beam-Wave Electronics (World Scientific, Singapore/New Jersey/London/Hong Kong, 1996) (ii) Technical Writing (Prentice-Hall of India, New Delhi, 2007), (iii) Engineering Electromagnetics Essentials (Universities Press, Hyderabad, 2015) (distributed by Orient Blackswan, India) and (iv) High Power Microwave Tubes: Basics and Trends (IOP Concise Physics; Morgan & Claypool Publishers, London, 2018) (with Vishal Kesari as the co-author). He is on the Editorial Board of the Journal of Electromagnetic Waves and Applications and he guest-edited a Special Issue on Microwave Tubes and Applications: Issue 17, Vol 31, 2017 of the Journal of Electromagnetic Waves and Applications (Taylor and Francis publication). He served on the Technical Committee on Vacuum Electronic Devices of the IEEE Electron Devices Society. He is a recipient of the SVC Aiya Memorial Award of IETE, Lifetime Achievement Award of the Vacuum Electronic Devices and Application Society, India and ISM Microwave Pioneer Award, Bengaluru.
