About
Raghavendra G. Kulkarni received B.E. in Electronics and Communication Engineering from Karnatak University in 1979, M.Tech. in Electrical Engineering from IIT Madras in 1982, and Ph.D. from IIT Kharagpur in 1998. He joined Hybrid Microcircuits (HMC) division of Bharat Electronics Ltd., (BEL) Bengaluru in 1982 as Deputy Engineer and developed several Surface Acoustic Wave (SAW) devices for commercial and defence applications. From 1998 to 2014, Dr. Kulkarni, in various capacities, successfully led a team of R & D engineers for development of SAW devices, thickfilm & thinfilm HMCs, and MEMS pressure transducers for strategic applications. Dr. Kulkarni won two BEL R & D Excellence Awards, one in 1989 for development of SAW filters used in TV receivers, and the second in 2011 for development of HMCs used in missile telemetry. In November 2013, he received RakshaMantri Award for development of electronic modules for missiles. Dr. Kulkarni has obtained two patents on SAW devices and has authored more than eighty papers in the field of SAW devices, signal processing, and mathematics. He is the inventor of several window functions like polynomial windows, hyperbolic cosine windows, and sine windows, for signal processing applications. In September 2014, Dr. Kulkarni joined PES University, Bengaluru, as Distinguished Professor in the Department of Electronics & Communication Engineering. He is a senior member of IEEE, life member ofRamanujan Mathematical Society, Indian Mathematical Society, and IMAPSIndia. He has given invited talks at TIFR Mumbai, IIT Delhi, SSPL Delhi, IGCAR Kalpakkam, LRDE Bangalore, IISc Bengaluru, Defence Lab Jodhpur, etc., and conducted workshops on design of SAW filters at ISRO and BEL, Bengaluru. Dr Kulkarni received outstanding educator award for the year 2023 from IEEE AP/MTT Society Bangalore chapter for his outstanding contribution to the antenna/microwave education. He also received Protsahan award for the journal paper publications in the field of communication engineering from IEEE COmSoc Bangalore chapter.
