About the Author: Dr Raveendranath U. Nair is currently Senior Principal Scientist and Head at the Centre for Electromagnetics (CEM), CSIR-National Aerospace Laboratories (CSIR-NAL), Bangalore, India. Dr R U Nair has authored/co-authored over 150 research publications including peer-reviewed journal papers, symposium papers and technical reports. He has co-authored a chapter in a book "Sensors Update" published by Wiley-VCH, Germany, in 2000. The electromagnetic (EM) material characterization techniques developed for his doctoral work were included in the section "Perturbation Theory" in "RF and Microwave Encyclopaedia" (Vol. 4) published by John Wiley & Sons, USA in 2005. Dr. Nair received the CSIR-NAL Excellence in Research Award (2007-2008) for his contributions to the EM design of variable thickness airborne radomes. His research interests include electromagnetic (EM) design and performance analysis of radomes, radar cross-section, frequency selective surfaces (for radomes and radar absorbing structures (RAS)), EM material characterization, complex media electromagnetics and microwave measurements. He took key responsibilities in the setting up of three major national facilities (Adaptive Antenna Facility, Frequency selective surface (FSS) Characterization Facility, and Electromagnetic Materials Applications Facility) at CEM, CSIR-NAL, Bangalore. He is a life member of the Aeronautical Society of India (AeSI), member of the Indian Society for Advancement of Materials and Processing Engineering (ISAMPE) and member of the Institute of Electrical and Electronics Engineers (IEEE). Dr R U Nair is also a Professor in the Academy of Scientific and Innovative Research (AcSIR), New Delhi.
