EE Team Awarded IEEE MTT-S 2021 Microwave Magazine Best Paper Award
March 19, 2021
The 2021 Microwave Magazine Best Paper Award is awarded to Negar Reiskarimian (lead author, former PhD student), Aravind Nagulu (current PhD student), Tolga Dinc (former PhD student) and Harish Krishnaswamy (EE Professor) for their paper entitled: "Nonrecipricol Electronic Devices: A Hypothesis Turned Into Reality."
The propagation of electromagnetic waves remains unchanged when the location of the transmitter "sender" and the receiver "listener" are swapped, and this is the principle of reciprocity. Violating the principle of reciprocity enables devices with "one-way" propagation such as circulators and isolators. These one-way propagating devices find a wide range of applications in wireless communication, radar systems, imaging, and sensing systems, and quantum computers. Traditional methods to realize these one-way devices use magnets and are hard to integrate with semiconductor fabrication which is the backbone of modern-day electronics. Research efforts from the CoSMIC lab in using time-modulation as a tool to replace magnetic bias have enabled generations of non-reciprocal devices that can be integrated on a chip and reaching stringent performance targets including high power handling, wide bandwidths, low noise, and small implementation area. Such devices can be easily integrated into compact, low-cost, portable devices such as VR headsets, and smartphones as well as performance stringent systems such as radio base stations and radar systems using in automotive and defense industries.
“We are extremely honored to receive this Best Paper Award, especially since the IEEE Microwave Magazine publishes top quality review papers that make the subject matter accessible to the broader engineering community.”
Negar Reiskarimian is a former PhD student from CoSMIC lab and is currently an Assistant Professor at Texas Instruments.
Aravind Nagulu is currently a fifth-year Ph.D. student in the Department of Electrical Engineering at Columbia University. He received his B.Tech. and M.Tech. degrees in electrical engineering from IIT Madras, Chennai, India, in 2016. Currently, he is investigating the application of time-modulation-based devices in next-generation wireless, medical and quantum systems.
Tolga Dinc is a former PhD student who is currently with Texas Instruments.
This research was funded by the NSF EFRI program, the AFOSR MURI program and the DARPA SPAR program.
