Frequency selective surface is a two dimensional passive array which shows filter characteristics for Electromagnetics wave impinging on its surface. Due to its spatial filter characteristics, FSS is widely used for aerospace applications such as antennas, radomes, and RAS. FSS is basically used in the design of antenna and radome to enhance their EM performance within the specified band and out-of-band RCS reduction. It is also used to design thin and broadband radar absorbing structures (RAS). In order to design FSS-based antennas, radomes, and RAS, it is essential to understand the fundamentals of FSS structure and its EM design methodologies for a particular application. In view of this, the present talk includes the fundamentals of FSS structures followed by its detailed applications to radomes, antenna, and RAS.    

Biography:

Dr Shiv Narayan obtained the Ph.D. degree in Electronics Engineering from Indian Institute of Technology (IIT-BHU), Banaras Hindu University, Varanasi, India in August 2006. He is associated with the Centre for Electromagnetics (CEM) of CSIR-National Aerospace Laboratories (CSIR-NAL), Bangalore, India since May 2008. Currently, He is holding the position of Principal Scientist at CEM, CSIR-NAL. Earlier, he held the position of Scientist-B in SAMEER (Society for Applied Microwave Electronics Engineering and Research), Kolkata, India, during the period March 2007-May 2008, where he was actively involved in the pattern synthesis of planar phased array antennas.
His research interests are broadly in the field of Electromagnetic applications and the topics include: Frequency selective surfaces (FSS), RAS, Radome, metamaterials, numerical methods in electromagnetics, antennas, pattern synthesis of antenna array, and EM material characterizations. Particularly, he is working on the design and analysis of FSS structures based on advanced numerical techniques (i.e. MM-GSM, TLTMM, and FDTD method) for aerospace applications for the last eight years. Dr Shiv is the author/ co-author of over 100 technical documents including peer reviewed journal and conference papers. He has published Technical Briefs (Books) with Springer on various topic such as ‘FSS Technology for the Design of High Performance Antennas’ and FDTD modeling inside Microwave Cavities. Dr Narayan was awarded with “Excellence Award in Research” for the year 2018-19 from CSIR-NAL for his significant contributions to the Electromagnetic Design and Development of FSS structures for Airborne Applications such as radomes, RAS, and antennas. Recently, he was awarded with prestigious CSIR- Raman Research Fellowship for the year 2019-20 and visited College of Engineering, San Diego State University, San Diego, CA, USA.
He is the reviewers of several prestigious International Journals published by IEEE Transactions on AP, IEEE AWPL, IEEE MTT, IEEE Sensors, Elsevier, Cambridge University Press, Springer Nature, and Tech Science Press, etc.
He is a life member of ISAMPE, India.
