Dr Lalit Kumar, Addl Director, Microwave Tube Research & Development Centre (MTRDC), Bangalore, obtained his MSc (Physics) from Meerut University in 1973 and PhD (Physics) from BITS, Pilani in 1980. He worked as a scientist at the Central Electronics Engineering Research Institute, Pilani, during 1978-97. He was a DAAD Research Fellow in Germany during 1983-85 and worked at the University of Tuebingen, and Philips, Hamburg. He was awARDEd Honorary Visiting Research Fellowship at Lancaster University, UK, during 1990-91 and in 1994.
Dr Kumar is at the MTRDC since 1997 and has made significant contributions in the development of coaxial magnetron, helix, and coupled-cavity travelling wave tubes, gyrotron, and computer-aided design codes for electron guns, depressed collectors, and slow-wave structures. His current interests include microwave power modules and ultra high power microwave devices.
He is the recepient of JC Bose Memorial Award (IETE) and Best Project Award (CEERl) both in 1993, and IETE-IRSI (83) Award-2001. He is a Fellow of lETE and a member of Indian Physics Association, Indian Vacuum Society, and Magnetics Society of lndia.
Dr UK Revankar obtained his ME in Electrical Communication in 1974 and PhD in Microwaves in 1996, both from the Indian Institute of Science, Bangalore. He joined LRDE, Bangalore in 1974 and since then, has contributed significantly in the indigenous design and development of low-noise radar receivers, low-phase noise frequency synthesisers/radar exciters, solid state transmitters, microstrip antennas/arrays, and active aperture arrays involving MIC /MMIC technology as applied to radar system.
Presently, as Project Director of R&D Group in RF/microwaves and distributed array controller, he has contributed significantly towards the development of active aperture arrays for modern active phased array radar. He has done pioneering work in active array technology resulting in realisation of L-band transmit/receive (T/R) module-based active array. His research experience has resulted in a large size microstrip antenna array in X-band for a light weight man-portable radar for the first time in the country.
He is the recepient of IETE-IRSI (83) Award-1997 and has also received many DRDO cash awards/technology awards. He is a Fellow of IETE. He has 14 papers to his credit and has presented 29 papers in international/ national conferences/symposia.
Dr S Christopher obtained his MTech from lIT, Kharagpur, and PhD in Engineering from lIT, Madras, in 1985. Microwave engineering, electronics, and radar systems are the main areas of his interest. He served as Project Associate during 1980-85 at lIT, Madras and later, as Senior Engineer during 1985-88 at BEL, Ghaziabad.
Dr Christopher joined LRDE, Bangalore, in 1988 and has worked in various capacities. Over the years, he has developed the slotted array technology and has developed required design tools, and copyright/patents have been received for many of these tools. He also served as the project manager for the development of radar for the ASP programme. At present, he is the project DIRECTOR responsible for LCA-MMR, MBA, ALH Radar and various resource generation projects. He has developed software for the near-field antenna measurement technique and has set-up India's first planar near-field measurement facility. Later, he extended the technique to cylindrical planar arrays such as Rajendra Radar class of array antenna. As project DIRECTOR, he has developed the indigenous maritime patrol radar-supervision (SV-2000) for the Navy.
A Fellow of the Institution of IETE, he is a member of SEE and IEEE also. He is the recipient of DRDO Scientist of the Year Award-1998, IETE JC Bose Memorial Award, and DRDO cash awards/technological awards.
