FlexICoN's Negar Reiskarimian wins a prestigious IEEE MTT-S Graduate Fellowship

Negar Reiskarimian, a Ph.D. student in Prof. Harish Krishnaswamy’s Columbia high-Speed and MmWave IC (CoSMIC) Lab has been awarded an IEEE Microwave Theory and Techniques Society (MTT-S) Graduate Fellowship for 2017. This is the highest honor that the IEEE MTT-S gives to top graduate students recognizing their research activities and promise in microwave engineering. Negar is the fourth Columbia Ph.D. student, and the third CoSMIC Lab member, to have won this prestigious award since 2013. Negar will be presented with the award at the 2017 IEEE International Microwave Symposium (IMS), which will be held June in Honolulu, Hawaii.

This award recognize Negar’s doctoral research entitled “Enabling Fully-Integrated Magnetic-Free Non-Reciprocal Antenna Interfaces by Breaking Lorentz Reciprocity: From Physics to Applications.” Negar’s research addresses the theory, design, and experimental validation of analog/RF/millimeter-wave integrated circuits and systems, with particular focus on novel non-reciprocal components for emerging wireless communication paradigms.

Most recently, Negar’s work on breaking reciprocity through the use of linear, periodically time-varying (LPTV) circuitshas resulted in the first integrated passive magnetic-free circulator built on a CMOS platform. The circulator has a much smaller form factor compared to magnetic counterparts and achieves low loss, high isolation, and high transmitter to receiver isolation. The novel circulator structure and receiver constitute a full-duplex receiver architecture that achieves state-of-the-art performance when compared to prior full-duplex receivers that integrate a shared-antenna interface on-chip. Negar’s work has been published in Nature Communications and International Solid-State Circuit Conference (ISSCC).
