    Welcome to the SCV-APS web site. Meetings are now being scheduled for the summer and fall. We welcome suggestions for topics and speakers for future meetings.

Upcoming Events

Next Meeting:

The July 6 meeting will feature Prof. Buon Kiong Lau, an Antennas and Propagation Society Distinguished Lecturer from the Department of Electrical and Information Technology Lund University,  Sweden.

The meeting will be at Texas Instruments Building E, 2900 Semiconductor Drive Santa Clara, CA 95051

The meeting will start at 6:30 PM with food and beverages with the lecture starting at 7:00 PM

 Dr. Lau will present a talk on “For Better, For Worse – A Story of Two Dipoles”

Mutual coupling is an important topic in the field of electromagnetics, as many practical applications call for multiple antennas to be located in close proximity to one another. It is also a persistent and fascinating topic, in which many new results and insights continue to be produced over the years. For simplicity, and with no loss in generality, many of the fundamental studies are based on this simple case of two parallel, half-wavelength dipole antennas.

In this lecture, I will focus on the mutual coupling of two dipoles in the context of wireless communications. I will begin by describing several performance metrics for characterizing the performance of two dipoles. I will then describe the impact of mutual coupling on the dipoles’ performance, as well as different approaches devised to compensate for the negative effects of coupling, illustrated with numerical examples. I will also comment on the relevance of the dipole based studies in the general context and some common pitfalls in existing studies on mutual coupling. I will finish with an outlook on opportunities for future work in this topic.

Buon Kiong Lau received the B.E. degree (with honors) from the University of Western Australia, Perth, Australia, and the Ph.D. degree from the Curtin University of Technology, Perth, Australia, in 1998 and 2003, respectively, both in electrical engineering. During 2000 to 2001, he was a Research Engineer with Ericsson Research, Kista, Sweden. From 2003 to 2004, he was a Guest Research Fellow at the Department of Signal Processing, Blekinge Institute of Technology, Sweden. Since 2004, he has been with the Department of Electrical and Information Technology, Lund University, where he is now a Professor in the Communications Group. He also holds a Senior Researcher appointment with the Swedish Research Council since 2010.

Dr Lau’s primary research interests are in various aspects of multiple antenna systems, particularly the interplay between antennas, propagation channels, and signal processing. He has co-authored 34 journal papers (17 in IEEE Transactions on Antennas and Propagation), 5 book chapters, over 100 conference papers and 3 patents/patent applications.

Dr. Lau has been an Associate Editor, a Senior Associate Editor and a Track Editor for the IEEE Transactions on Antennas and Propagation, for which he was also a Guest Editor of the “Special Issue on MIMO Technology” (2012) and the Lead Guest Editor of the “Special Issue on Theory and Applications of Characteristic Modes” (2016). In addition, he was the Lead Guest Editor of the “Special Cluster on Terminal Antenna Systems for 4G and Beyond” (2013) for the IEEE Antennas and Wireless Propagation Letters.

From 2007 to 2010, he was the Co-Chair of Subworking Group 2.2 on “Compact Antenna Systems for Terminals” within EU COST Action 2100. He has also served as a Swedish National Delegate and the Chair of Subworking Group 1.1 on “Antenna System Aspects” within COST IC1004 between 2001 and 2015. From 2012-2015, he was the elected Regional Delegate of European Association on Antennas and Propagation (EurAAP) for Region 6. He is also a member of the Education Committee within the IEEE Antennas and Propagation Society (AP-S), where he had been the Coordinator for the annual IEEE AP-S Student Design Contest during 2013-2015.

In 2015, Dr. Lau received an award from IEEE Transactions on Antennas and Propagation for exceptional performance as an Associate Editor (one of 3 awarded among 46 Associate Editors). His co-authored papers have received several Best Paper Awards, including two CST University Publication Awards in 2010 and 2013
