Guru of University of Dayton

Thin film Barium Strontium Titanate (BaxSr1-xTiO3-henceforth BST) variable capacitor (varactor) tuning elements are key components for reconfigurable microwave circuits.  This talk will introduce the thin film varactors and their demonstrated applications. The size, weight, and power (SWaP) savings using the chip scale tunable RF front end components is a game-changer for defense applications and key for the 5G/6G cellular communications.

Biography:

Professor Subramanyam received his PhD degree in Electrical Engineering  from the University of Cincinnati in 1993.  He is currently a Professor of Electrical and Computer Engineering at the University of Dayton.  He served as the Chair of the Department of Electrical and Computer Engineering from 2010-18.  He has published over 175 refereed journal and conference papers in the area of Electronic materials and devices.  His current research involves oxide thin films for reconfigurable RF/microwave circuits, and sensors.  He has been collaborating with the Air Force Research Laboratory (AFRL) in these areas since 2000.  His work to date has been funded by NASA, AFRL, AFOSR, NSF, and DARPA.  Professor Subramanyam won the 2008 Alumni award for Scholarship at the University of Dayton, and 2007 IEEE Harrell Noble Award from the IEEE Dayton Section.  In 2013, University of Dayton opened the Center of Excellence for Thin-film Research and Surface Engineering (CETRASE) under his leadership. He is currently the Chair of the IEEE Dayton section, and Region 2 Coordinator for the IEEE Microwave Theory and Technology Society (MTTS).
