Over de auteur
John Huang, Ph D, has been with the Jet Propulsion Laboratory, California Institute of Technology, since 1980, where his research activities involve microstrip antennas, mobile vehicle antennas, antenna miniaturization techniques, spacecraft antennas, phased arrays, reflectarrays, and inflatable antennas. He pioneered the development of several major antenna technologies, such as the microstrip reflectarray and the inflatable array antenna. Dr. Huang, an IEEE Fellow, has published extensively and received four U.S. patents and more than twenty NASA Certificates of Recognition.
José A. Encinar, Ph D, 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.
