Dan SievenpiperProfessor Dan Sievenpiper joined the UC San Diego faculty in 2010. He received his BS in 1994 and his PhD in 1999 from UCLA, where he studied photonic crystals and other periodic structures, and invented the high impedance electromagnetic surface. Dan joined HRL (the former Hughes Research Laboratories) in Malibu, CA in 1999. During the following 11 years, he and his team developed new electromagnetic structures, with an emphasis on small, conformal, tunable, and steerable antennas. Dan held a variety of technical and management positions at HRL including Director of the Applied Electromagnetics Laboratory. In 2010 he joined UC San Diego, where his research is focused on artificial media, and the integration of active electronics with electromagnetic structures and antennas to enable new capabilities and applications. In 2008, Dan received the URSI Issac Koga Gold Medal, and also the IEEE Antennas and Propagation Society Piergiorgio Uslenghi Letters Prize Paper Award. In 2009, he was named as a Fellow of the IEEE, and in 2019, he was awarded the John D. Kraus Antenna Award. During 2010-2017, Dan served as an associate editor of IEEE Antennas and Wireless Propagation Letters. He also served as the chair of the IEEE Antennas and Propagation Society Administrative Committee on New Technology Directions from 2013-2014, and as the general chair of the IEEE Antennas and Propagation Symposium and URSI Radio Science Meeting which was held in San Diego in 2017. He has served as the vice chair of the ECE department from 2019 to present. Dan currently has more than 80 issued patents and more than 200 publications.

Dr. Matthew C. Smith is dual-degreed with a BSEE and a BSNS from USF. He received his MSEE in 2019 and Ph.D. in 2022 in applied electromagnetics from UCSD with focused research on complex E-field pattern synthesis techniques in conductive media (e.g., biological tissue) using multichannel coil arrays. Currently, he is a Post-Doc Scholar/Researcher at UCSD in the Applied Electromagnetics Group under Prof. Daniel Sievenpiper. His primary research areas include self-activated cavity absorbers, rf-plasma interactions, electrically small wideband tunable antennas, and bioelectromagnetics. He retired from Raytheon Space and Airborne Systems in El Segundo, CA in 2017. As a Senior Engineering Fellow at Raytheon for over 25 years, he specialized in microwave and millimeter-wave circuits, subsystems, and systems for radar, remote sensing, communications, and EW systems. His design experience includes over fifty fielded and on-orbit microwave and millimeter-wave circuit designs, seven patents (two are NIST validated), and over twenty IEEE/SPIE publications from VHF to W-Band. He is a Senior Member of IEEE.
