In modern societies, we are increasing our reliance on widespread technological advancements in computer and electronic systems. The diverse activities of our society such as communication (voice and data), emergency management, air-traffic safety and control, law-enforcement (police and fire), ambulance, hospitals and commerce (both internet and otherwise), have become increasingly dependent on these advancements in technology. Such sophistication comes with a price of vulnerability from a wide variety of threats. There is a diversity of threats, one of which is natural lightning, which happens to be the only threat made by nature. The remainder such as Nuclear Electromagnetic pulse (NEMP), High-Power Microwaves (HPM), and Short Pulse Technologies (also called Ultra-Wideband) are all made by mankind. HPM and Short Pulse technologies have beneficial applications as well. However, when such environments are created with a purpose of damaging electrical and electronic systems, it is classified as the Intentional Electromagnetic Environment or the IEMI. These threats can affect military assets, as well as civilian infrastructure. The effect or impact of an incident high-power electromagnetic environment on an electronic victim system may be natural, accidental, or intentional. In this presentation we will look at some examples of such incidents, including a commercial airline crash, as well as beneficial applications of electromagnetic energy.
Dr. Giri obtained his Master's in Engineering from IISc, Bengaluru in 1969 followed by MS in 1973 and PhD in 1975 from Harvard University. Additionally, he completed a certificate course on Harvard Introduction to Business Program in 1981. Since 1984, he has been a consultant performing R&D work for US Government and Industry. He is an Adjunct Professor in the Department of ECE, University, Albuquerque, NM, USA. Dr. Giri taught graduate and undergraduate courses in the Dept. of EECS, University of California, Berkeley campus. Dr. Giri was a Research Associate for the National Research Council at the Air Force Research Laboratory (AFRL), Kirtland AFB, New Mexico, USA, where he conducted research in EMP and other aspects of electromagnetic theory.
Dr. Giri has a rich experience in the field of electromagnetic theory and its applications in NEMP (Nuclear Electromagnetic Pulse), HPM (High-Power Microwaves), Lightning, and UWB (Ultra-Wideband). He has published three books. He received Hind Rattan Award during Indian Republic Day in 2017. He served as a Visiting Scientist in ISAC, ISRO, Bengaluru in 1981 for 7 months and also served as IISc BEL Visiting Professor in the ECE Dept of IISc in 2018.
