Low Radar Cross Section HIS-Based Phased Array

Dr. Hema Singh is working as Senior Principal Scientist in Centre for Electromagnetics, National Aerospace Laboratories (CSIR-NAL), Bangalore, India. She received Ph.D. degree in Electronics Engineering from IIT-BHU, Varanasi India in Feb. 2000. For the period 1999-2001, she was Lecturer in Physics at P.G. College, Kashipur, Uttaranchal, India. She was a Lecturer in EEE of Birla Institute of Technology & Science (BITS), Pilani, Rajasthan, India, for the period 2001-2004. She joined CSIR-NAL as Scientist in January 2005. Her focus area of research is indigenous development of stealth technology, one of the critical challenges in the country’s self-reliance in strategic sector. Mr. Avinash Singh is a Ph.D. scholar in the department of Electronics and Communication of Indian Institute of Technology (IIT), Roorkee, India. He has worked as Project Assistant at the Centre for Electromagnetics (CEM) of CSIR-National Aerospace Laboratories, Bangalore for two and half years. He has obtained integrated B.Tech. and M.Tech. (Electronics and Communication) from Amity University, Jaipur, India in 2016. His research interests are Phased arrays: corporate-fed planar/conformal patch array with conventional/HIS-based ground plane, Active RCS Reduction in Phased Arrays, Estimation and control of RCS of Phased Arrays, EM design and Analysis of Multi-layered Radar Absorbing Structures (RAS), and millimeter wave antenna arrays.
