About the Author
Dr. Nitin Afzulpurkar started his research in late 80s focusing on robotics especially parallel robotic architectures and their implementations on transputer networks. He published several journal papers in this area and received a best conference paper award in 1989 in New Zealand. In the mid 90s his research interests turned to computer vision and its application for robotics. Here his initial work was on stereo vision algorithms and its implementation on robotic platforms. Currently one main area of his research is still computer vision with focus on tracking and identification of human, emotion and gesture recognition, application of machine vision for electronics industry. He has published extensively in international journals and conferences with two international best paper awards (Germany and Croatia) and has received three US patents in this area. In early 2000 he started his research on Microelectromechanical systems (MEMS) which forms a major area of his current research. He has published several papers in the top Journals in MEMS area and his book titled "Microfluidics and BioMEMS: Design, Fabrication and Applications" was published in 2009.
Dr Vishnu Srivastava is presently working as Chief Scientist and Head of the Microwave Tubes Division, CSIR-Central Electronics Engineering Research Institute (CSIR-CEERI), Pilani (Rajasthan), India, and as Professor of Ac-SIR (Academy for Scientific and Innovative Research, New Delhi). He received MSc degree in Physics from Rajasthan University, Jaipur, in 1975, and Ph.D. degree in Engineering from Lancaster University, U.K., in 1987. He was a commonwealth scholar from 1984 to 1987 in the UK, and was Junior Research Fellow at Rajasthan University during 1975. He joined CSIR-CEERI, Pilani in January 1976. At CEERI, he was involved with the design and development of various types of high power vacuum microwave devices for communication and Radars. He developed X-band 200kW tunable Coaxial Magnetron for ECCM Radars. He developed space-qualified C-band 60W TWT and Ku-band 140W TWT for satellite communication. He developed SUNRAY-codes for small-signal and large signal analysis of beam-wave interaction in TWTs. His successfully developed SUNRAY-1D software code for multi-signal analysis of beam-wave interaction in TWTs, was exported to UK., and was also purchased by MTRDC (DRDO), Bangalore. He developed technologies for the successful development of high efficiency vacuum microwave amplifiers (Space TWTs) for satellite communication. Presently, he is associated with the design and development of vacuum microelectronic devices for THz communication – requiring innovations in MEMS technologies (UV LIGA processes) for such devices. He has more than 120 research publications in different national and international journals, and has already guided 8 PhD. students and more than 60 ME/MTech students. He received IETE - JC Bose memorial awards for best engineering paper and best project team . He is a fellow of IETE and VEDA Society, and senior member of IEEE , CSI, IPA, IVS, PSI and IFTA. Recently, he was awarded Honorary Fellowship of Society for Education & Research Development (SERD), New Delhi. His present interests are in the design and development of high efficiency, high power vacuum microelectronic devices for mm- and sub-mm-wave frequencies.
