Steven A. Cummer

Bass Fellow

Steven A. Cummer is currently Professor of Electrical and Computer Engineering at Duke University. He received his Ph.D. in Electrical Engineering from Stanford University in 1997 and spent two years at NASA Goddard Space Flight Center as a National Research Council postdoctoral research associate before joining Duke. He has written or coauthored more than 170 papers in refereed journals, is a Fellow of the IEEE, and received a Presidential Early Career Award for Scientists and Engineers (PECASE) in 2001. His current CMIP-related work is in a variety of theoretical and experimental topics related to engineered electromagnetic and acoustic materials.

Cummer's research interests include design, simulation, and demonstration of artificial structures and materials for manipulating electromagnetic and acoustic waves. Cummer’s group currently has primary interests in passive and active acoustic metamaterials, and in active electromagnetic structures that combine circuit functionality and metamaterials concepts.
