About Me

Andrés Alayón Glazunov was born in Havana, Cuba. He received the M.Sc. (Engineer-Researcher) degree in physical engineering from Peter the Great St. Petersburg Polytechnic University (Polytech), St. Petersburg, Russia, in 1994, the Ph.D. degree in electrical engineering from Lund University, Lund Sweden, in 2009, and the Docent (Habilitation) qualification in antenna systems from Chalmers University of Technology, Gothenburg, Sweden, in 2017. From 1996-2005, he held various research and specialist positions in the Telecom industry, e.g., Ericsson Research, Telia Research, and TeliaSonera, in Stockholm, Sweden. From 2001-2005, he was the Swedish delegate to the European Cost Action 273  and from 2018-2020 he was the Dutch delegate to the European Cost Action IRACON. He has been one of the pioneers in producing the first standardized OTA measurement techniques for 3GPP, and devising novel OTA techniques, e.g., the Random-LOS and the Hybrid antenna characterization setups.

He has contributed to or initiated various European research projects, e.g., more recently, the is3DMIMO, the WAVECOMBE and the Build-Wise projects under the auspices of the H2020 European Research and Innovation program. Dr. Glazunov has also contributed to the international 3GPP and the ITU standardization bodies. From 2009-2010, he held a Marie Curie Senior Research Fellowship at the Centre for Wireless Network Design, University of Bedfordshire, Luton, the U.K. From 2010-2014, he held a post-doctoral position with the Electromagnetic Engineering Laboratory, KTH-Royal Institute of Technology, Stockholm, Sweden. From 2014-2018, he held an Assistant Professor position at Chalmers University of Technology, Gothenburg, Sweden.

Dr. Glazunov is currently an Associate Professor with the Department of Electrical Engineering, University of Twente, Enschede, the Netherlands, where he is leading the Radio, Propagation and Antenna Systems research. And he is also an Affiliate Professor with the Chalmers University of Technology, Gothenburg, Sweden, where he is leading the OTA Characterization of Antenna Systems research area. He is the author of more than a hundred scientific and technical publications. He is the co-author and co-editor of the textbook LTE-Advanced and Next Generation Wireless Networks – Channel Modelling and Propagation (Wiley, 2012). His current research interests include, but are not limited to mmWave array antenna design, MIMO antenna systems, electromagnetic theory, fundamental limitations on antenna-channel interactions, radio propagation channel measurements, modeling and simulations, wireless performance in the built environment, and the OTA characterization of antenna systems and wireless devices.

Education

I'm teaching and coordinating an MSc level course on MIMO systems, channels and antennas. The course gives some fundamental notions on MIMO channels, algorithms and performance metrics. MIMO antenna systems are a fundamental ingredient of 4G, 5G and Beyond 5G wireless systems. 

I offer a variety of BSc and MSc thesis projects covering both theoretical and more practical aspects of antennas and propagation, related to antenna design, antenna characterization techniques, channel measurements, and modelling, as well as MIMO/Massive MIMO topics.

Courses Academic Year  2021/2022

Courses in the current academic year are added at the moment they are finalised in the Osiris system. Therefore it is possible that the list is not yet complete for the whole academic year.
