2012 IEEE International

William Chappell

William Chappell joined DARPA as a program manager in July 2011. His interests include advanced packaging, adaptable RF systems, and antenna arrays.

Dr. Chappell came to DARPA from Purdue University, where he served as an associate professor in the Electrical and Computer Engineering (ECE) department. His research focus has been on wireless components, specifically the unique integration of RF and Microwave components based on electromagnetic analysis. This has ranged from advanced RF sensors such as miniature RF Ion Trap Mass Spectrometry to advanced digital-at-every element antenna arrays. A particular focus has been the development of adaptable RF systems, particularly focusing on the tunable preselects filters. He has shown the ability to design a single RF system that is adaptable to numerous application areas and/or adjust to dynamic changes within the spectral environment.

Dr. Chappell is the recipient of numerous research and teaching awards. He has been the advisor of numerous IEEE MTT International Microwave Symposium best paper finalists. He was advisor of the first author and co-author of the paper selected best journal paper for the IEEE VT Society in 2009, for wearable multi-antenna systems demonstrating distributed wearable MIMO. In 2010, he and his student were selected for the Meritous Paper Award for the 2010 Gomactech conference for demonstrating adaptable array technologies through digitization at every element which self-corrected in extreme operating environments. In 2011, he received the ARL Director’s Coin his for work on Standoff Inverse Analysis and Manipulation of Electronic Systems Muri analyzing the effects of nonlinearities in high power systems. He was selected as a Collaborative Investigator by the Howard Hughes Medical Institute for work on RF implantable systems, and to join the Frontiers of Engineering meetings sponsored by the National Academies of Engineering.

Dr. Chappell received his Bachelor of Science in 1998 from the University of Michigan, where he graduated Summa Cum Laude. He went on to receive his Masters and Doctor of Philosophy. also from the University of Michigan, studying in the Radiation Laboratory on spectral isolation techniques for high frequency microwave systems.
