The Active Electromagnetics in Future Chip-Scale Systems: Diversity of Spectrum (RF-Terahertz-Optics) and Diversity of Applications by Professor Kaushik Sengupta (Princeton U)
Tuesday, Mar. 6
1 p.m. - 2 p.m. Location: ECSS 3.503

ABSTRACT: Being able to harness, synthesize, manipulate electromagnetic waves and transduce to and extract information from them forms the foundation of nearly all communication, sensing and imaging technologies that have transformed our lives and continue to do so. In the next few decades, this access is expected to expand orders of magnitude than ever before stretching from RF-to-THz-to-optical frequencies (GHz-PHz), creating a new generation of ubiquitous connected sensory technologies that not only allows us to interact with and monitor the physical world, but also learn, make intelligent decisions and perform autonomous actuation functions. Enabling these technologies that are extremely diverse across applications, spectrum and are multi-modal, reconfigurable and adaptable requires a new approach to synthesis and detection of the electromagnetic fields for information extraction and transduction.
In this talk, I will highlight some of our approaches to exploit electromagnetic interactions at sub-wavelength scales across these wide dimensional wavelengths (10 mm-500 nm) spanning across mm-Wave, THz and visible range frequencies in ICs, to enable new architectures and functionalities. In particular, will focus on three frequency/wavelength ranges to 1) (30-100 GHz) Frequency and EM-reconfigurable transceiver architectures for generalized scalable MIMO arrays 2) (100-1000 GHz) Universal chip-scale Active THz surfaces 3) (500-1000 nm) External optics-free fully integrated nano-optical systems in silicon (<10mm3 in volume) with multi-functional nano-plasmonic structures and ~100fM sensitivity. The latter can enable a new class of ultra-miniaturized massively multiplexed optical sensors for in-vitro and in-vivo sensing, diagnostics and personalized health. Harnessing such a spectral expanse in one integrated platform with techniques combining circuits, electromagnetics, optics and signal processing can lead to new capabilities and open untapped opportunities across a wide range of applications in communication, sensing and imaging.
BIO: Kaushik Sengupta received the B.Tech. and M.Tech. degrees in electronics and electrical communication engineering from IIT Kharagpur, Kharagpur, India, in 2007, and the M.S. and Ph.D. degrees in electrical engineering from the California Institute of Technology (Caltech), Pasadena, CA, USA, in 2008 and 2012, respectively. He worked in the University of Southern California, Los Angeles, CA, USA, in 2005 and the Massachusetts Institute of Technology, Cambridge, MA, USA, in 2006, where he was involved in nonlinear integrated systems for high-purity signal generation and low-power RF identification tags. In 2013, he joined the Department of Electrical Engineering, Princeton University, Princeton, NJ, USA, as a Faculty Member. His current research interests include high-frequency ICs, electromagnetics, and optics for various applications in sensing, imaging, and high-speed communication.
Dr. Sengupta received the Bell Labs Prize (2017), Young Investigator Program (YIP) Award from the Office of Naval Research in 2017, the DARPA Young Faculty Award (2018) and the Charles Wilts Prize in 2013 from the Department of Electrical Engineering, Caltech, for outstanding independent research in electrical engineering leading to a Ph.D. He serves on the Technical Program Committee of the IEEE ESSCIRC, IEEE CICC and PIERS. He was four times selected to the Princeton Engineering Commendation List for Outstanding Teaching in 2014, 2016, 2017 and 2018 and received the prestigious ‘Excellence in teaching Award’ form the School of Engineering  nominated by the Undergraduate and graduate student council. He received the Prime Minister Gold Medal Award of IIT Kharagpur in 2007, the IEEE RFIC Symposium Best Student Paper Award (1st prize) in 2012 and the 2015 IEEE MTT-S Microwave Prize.
