Omeed Momeni Named PI in NSF Grant Project

The National Science Foundation’s Division of Electrical, Communications and Cyber Systems (ECCS) has awarded a three-year grant of $219,994 to Omeed Momeni, an assistant professor in the UC Davis Department of Electrical and Computer Engineering. His project, titled “Terahertz PLL-Based Phased Array for Wide-Band Radar/Sensing Systems in Silicon,” is a collaborative endeavor between UC Davis and UC Irvine.UC Davis Prof. Omeed Momeni

Momeni will lead efforts to implement a scalable, high-power terahertz (THz)-phased array transmitter for various radar and sensing applications. Current THz systems employ expensive and bulky devices for high-resolution radar, 3D imaging, security screening and the detection of concealed weapons. Momeni’s project introduces a novel methodology to implement a compact, on-chip THz system that will overcome the many challenges facing such high-frequency systems. “Lossy” phase shifters, and the complications of integrating a locked signal with a phased array system, have complicated earlier efforts in this field; Momeni has proposed a novel phase-locked loop (PLL) architecture that will help increase output power and tuning range, while lowering unwanted phase noise.

Momeni earned his undergraduate degree in electrical engineering at Iran’s Isfahan University of Technology. He came to the United States to pursue post-graduate degrees in the same field, while working as a design engineer at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. He obtain a master’s degree at USC in 2006, and a doctorate at Cornell University in 2011. He then joined the UC Davis College of Engineering faculty, while also serving a one-year stint as a visiting professor at UC Irvine, from 2011–12.

The NSF’s Division of Electrical, Communications and Cyber Systems addresses fundamental research issues underlying device and component technologies, power, controls, computation, networking, communications and cyber technologies. ECCS supports the integration and networking of intelligent systems principles at the nano, micro and macro scales, for a variety of application domains in healthcare, homeland security, disaster mitigation, energy, telecommunications, the environment, transportation, manufacturing and other systems-related areas.
