Biography
Guru Subramanyam is currently a Professor and School of Engineering Faculty Fellow in the Department of Electrical and Computer Engineering, at the University of Dayton. He received his PhD (1993) and MSEE (1988) degrees in Electrical Engineering with specialization in Microelectronics from the University of Cincinnati, following his BE degree in Electrical and Electronics Engineering from the PSG College of Technology, (then affiliated with University of Madras) in 1984. He has published over 175 refereed journal and conference papers in the areas of thin film materials and devices and holds eight patents. His current research involves oxide thin films including reconfigurable microwave circuits, phase change materials, and memristors for neuromorphic computing. He has been collaborating with the Air Force Research Laboratory (AFRL) since 2000. His work to date has been funded by NASA, AFRL, AFOSR, NSF, DARPA, NSTXL (Microelectronics Commons Program), and several companies including Lockheed Martin, Northrop Grumman, Rockwell Collins, and Indiana Microelectronics. His research funding at the University of Dayton exceeds $10M to date. Professor Subramanyam won the 2008 Alumni Award for Scholarship at the University of Dayton, and 2007 IEEE Dayton section Harrell Noble Award for his achievements in electronic devices. In 2010, he was recognized by the Affiliate Societies Council of Dayton as one of the outstanding engineers/scientists in the Dayton area in the category of research. This award included a proclamation from the Ohio State Assembly. In 2013, University of Dayton opened the Center of Excellence for Thin-film Research and Surface Engineering (CETRASE) under Professor Subramanyam’s leadership. In 2024, he was recognized as a Distinguished Professor and the School of Engineering Faculty Fellow at the University of Dayton. He is a Senior Member of IEEE and currently serving as the Region2 coordinator for the Microwave Theory and Technology Society (MTT-S).
Presentations
Multifunctional Oxide Thin Film Devices for 5G/6G Applications
This talk begins with an introduction to 5G/6G, and practical challenges in implementing 5G/6G technology. Integration of advanced multifunctional materials enables new functionalities for RF/microwave circuits for 5G/6G communication systems. This talk will introduce two thin film multifunctional oxide technologies. One is a thin film Barium Strontium Titanate (BaxSr1-xTiO3-henceforth BST) based variable capacitor (varactor) tuning element for reconfigurable microwave circuits and second is the use of phase change thin film Vanadium Dioxide (VO2) for reconfigurable intelligent surfaces (RIS). Details of the advanced thin film processes for the integration of BST thin film varactors and VO2 devices, their unique electromagnetic properties and their demonstrated microwave applications will be presented.
