Prof. Satheesh Bojja Venkatakrishnan received his Bachelor’s degree in electronics and communication engineering from the National Institute of Technology, Tiruchirappalli, in 2009, and graduated with his M.S. and Ph.D. degrees in electrical engineering from the Ohio State University (OSU), Columbus, OH, in 2017. Prior to this, he was a Scientist for DRDO, India from 2009 to 2013, working on the development and implementation of active electronic steerable antennas. He joined FIU as an ECE faculty in Fall 2022. His current research includes RF system design for secure wideband communications, data sensing and imaging, interference mitigation techniques, and RFSoC based Simultaneous Transmit and Receive System (STAR) to improve the spectral efficiency. In parallel, Dr. Bojja has been working on developing RF sensors and circuits including fully passive neural implants and multi-modal patch sensors for bio-medical applications. Dr. Bojja has won numerous awards and recognitions including the IEEE Electromagnetic Theory Symposium (EMTS-2019) Young Scientist Award, and the best paper award in the International Union of Radio Science General Assembly and Scientific Symposium (URSI-GASS) held at Montreal, Canada in Aug 2017. Recently, he also won the NSF-CRII award, often referred to as a “mini-career” award. He has published more than 26 peer reviewed articles, contributed to a book chapter on “wearable electronics”, and is co-inventor on 4 U.S. patents.

Description

Our reliance on wireless links and communications has become an integral part of our everyday life by facilitating reliable and secure communication, pervasive computing, and data storage resources. Consequently, we can expect strong and continuing interest in RF/microwave components for various day-to-day applications. However, with the growth of future wireless applications in augmented reality/virtual reality (AR/VR), autonomous driving, smart and connected devices, and wearable electronics, the microwave spectrum is becoming increasingly crowded, along with the burden to develop standardized protocols. Consequently, stringent restrictions are imposed on radio-frequency hardware.

Towards this, in this talk, I present the development of the next-generation fast, fully flexible, full-duplex radios (F4R) with adaptive RF front ends, that will form the fundamental building block of our connected world. These radios will play an integral part in national defense, radar and remote sensing, spectrum management, and terrestrial and space applications. In particular, this work will focus on co-designing antenna interfaces, RF frontends, analog and digital back-ends for novel radio architecture to enable efficient spectrum sharing via i) full-duplex operation, ii) adaptive access to underutilized spectral bands, and iii) interference suppression. This joint hardware-software approach will solve bottlenecks in existing systems and lead to the design of robust and efficient wireless networks and sensing technologies.
