Profile

Pragnan Chakravorty, Principal Director

Pragnan Chakravorty (VidwanID) received his B.E. degree in electronics engineering from Nagpur University, India; his M.Tech. degree in Radio-Frequency and Microwave Engineering from the Indian Institute of Technology, Kharagpur, India; and his Ph.D. degree in Electronics and Communication Engineering from the National Institute of Technology, Durgapur, India. He did a Post-Doctoral Research in CNRS-Lab-STICC, UBO, France and served as a full Professor in a couple of engineering colleges of India. He began his career as a lecturer in the year 2001. He is the Founder and Principal Director of Clique for Applied Research in Electronic Technology, His research interests include Semiconductor device modeling for RF-IC applications, mm-wave devices for beyond 5G communications and defense equipment, antenna arrays for pattern synthesis and signal processing, phased array radars, design of passive and active microwave circuits over different circuit board technologies, computational intelligence/AI for optimization and acoustic arrays. He is a Senior Member of IEEE, Fellow of IETE and Fellow of IEI with several publications in international journals and conference proceedings. Some of his research articles have been published in top journals like IEEE Transactions in Antenna Propagation, IEEE Antennas and Wireless Propagation Letters and so on. He served as a reviewer in many prestigious journals like IEEE Antennas and Wireless Propagation Letters, IEEE Transactions on Circuits and Systems-II, IEEE Transactions on Systems, Man and Cybernetics: Systems, IET Microwave and Antenna Propagation, IET Electronic Letters, IET Signal Processing, Journal of Acoustic Society of America, Applied Soft Computing to name a few. He made some outstanding contributions towards engineering sciences, for example, his article on a modified general diode equation, published in the IEEE Transactions on CAD of Integrated Circuits and Systems, makes him the only person in the World so far who has disproved a Nobel Laureate in Physics, i.e. William Shockley. Also, he has redefined the concept of signal in an article published in the, high impact, IEEE Signal Processing Magazine. In the year 2022, he was nominated for the most prestigious scientific award of India: The Shanti Swarup Bhatnagar Prize.
