Illustration of principles of advanced electronics and photonics by showing their applications in advanced radar, wired/wireless communications, and electronic sensing. Key electronics/photonics devices including high speed transistors, diodes, lasers, high frequency modulators, photodetectors, amplifiers, and passive circuitries are discussed. System applications including advanced radar system, radio over fiber, and millimeter wave /THz signal generation and processing are deliberated and analyzed.

Investigations of a fundamental and/or applied nature, intended to develop design techniques,research techniques, initiative, and independent inquiry. A written thesis must be completed in accordance with the rules of the Graduate School and the College of Engineering. Completion of the course requires a successful oral defense open to the public and a written thesis approved by the student's thesis committee unanimously and the ECE Graduate Program Director. Admission to the course is based on a formal thesis proposal endorsed by the student's graduate committee and submitted to the ECE Graduate Program Director.

For PhD students who plan to take the PhD Comprehensive exam within the next 3 months. Up to 6 credits may be applied to either doctoral dissertation or MS thesis (should student not pass Comprehensive exam). Graded P/F.

Dr. Yifei Li received his B.Eng. in Optoelectronics from Huazhong University of Science and Technology, China, in 1996. He received his MS (2001) and PhD (2003) in Electrical Engineering both from Drexel University, Philadelphia, PA. From 2003 to 2007, he was a research faculty with the Center for Microwave-Lightwave Engineering, Drexel University. In 2007, he joined the ECE Department of the University of Massachusetts Dartmouth, where he is currently a full professor and the director of the RF Photonics Lab. From 2013 to 2014, Dr. Li was a visiting faculty in the Optoelectronic Research Group of the University of California Santa Barbara. Dr. Li’s research interests includes RF photonics, photonic integrated circuits, coherent optical communications, RF devices and systems, and laser physics.

Dr. Li has five US patents in RF Photonics. He has numerous publications in renowned technical journals and international conference proceedings. Since he joined UMassD, he has led 8 competitive research projects funded from the Navy, Airforce and DARPA as the Principle investigator. Dr. Li was a winner of European Microwave Association (EuMA) Young Scientist Prize (1st prize) during the 12th Colloquium on Microwave Communications held in Budapest, Hungary. He was a winner of 2008 DARPA MTO Young Faculty Award.
