Encinar, PhD, has been at Universidad Politécnica de Madrid since 1980, where he became a Professor of the Electromagnetism and Circuit Theory Department in 1991. His research interests include numerical techniques for the analysis and design of multi-layer periodic structures, frequency selective surfaces, printed arrays, and reflectarrays. He has published extensively and holds three patents on array and reflectarray antennas. Dr. Encinar was a co-recipient of the 2005 H. A. Wheeler Applications Prize Paper Award, and the 2007 S. A. Schelkunoff Transactions Prize Paper Award, given by IEEE Antennas and Propagation Society. Show Less
