John Papapolymerou

RF MEMs, antennas

The next generation of high-frequency circuits for communication, sensor and radar systems is taking shape in the laboratory of Dr. John Papapolymerou, an assistant professor in the School of Electrical and Computer Engineering, where he is a member of the Electromagnetics and EDA Technical Interest Groups.

An internationally recognized authority on RF MEMs technology and the design and modeling of MEMs/electronic packages, Papapolymerou is focused on system-on-a-chip/system-on-a-package designs that will lead to smaller, lower-cost, high-performance, intelligent RF front-ends. He is also widely recognized for his contributions to the field of high-speed electronics characterization technology.

His research is laying the groundwork for devices such as remote sensors for detecting chemical or biological agents, high-resolution imaging arrays for radio astronomy, and more efficient broadband personal and satellite communication systems (e.g. wireless LANs).

In addition, Papapolymerou's research in RF MEMS is aimed at devising low-power intelligent circuits that will adapt to different situations. The reconfigurable designs have been used to create compact RF MEMS versions of filters, tuners and antennas.

In a related area, Papapolymerou and his team work with micromachining techniques to build low-loss wave-guiding structures capable of handling frequencies up to 5 THz.

His research interests also include the development of passive and active planar circuits on semiconductor (silicon, silicon-germanium and gallium arsenide) and organic substrates (liquid crystal polymer, low-temperature co-fired ceramic) for microwave and millimeter-wave applications, as well as RF packaging.

A 2004 recipient of the U.S. Army Research Office's Young Investigator Program Award, Papapolymerou serves as vice chair for Commission D of the U.S. National Committee of URSI. He was the commission's secretary last year and chair of the Atlanta IEEE MTT/AP chapter. Papapolymerou also holds an NSF CAREER Award.

Also in 2004, Papapolymerou received six invention disclosures and his writings appeared in two books and 20 journal papers. He conducted 46 conference presentations.

Papapolymerou earned his undergraduate degree in electrical and computer engineering from the National Technical University in Athens, Greece. His master's and doctorate were obtained at the University of Michigan, Ann Arbor.
