Hubregt J. Visser was born in Goes, The Netherlands, on October 26, 1964. He received the M.Sc. degree in electrical engineering from Eindhoven University of Technology, The Netherlands, in 1989. In 1990, after fulfilling his military service at TNO Physics and Electronics Laboratory, The Hague, The Netherlands, he joined the same laboratory as a civilian. He has participated in several projects concerning near-field antenna measurements, monolithic microwave integrated circuits design, and phased-array antenna design. From mid-1996 to mid-1997, he was stationed at the European Space Research and Technology Centre, RF Systems Division, Noordwijk, The Netherlands, where he worked on array antenna modeling. In 2001 he joined TNO Science and Industry, Eindhoven, The Netherlands where he has been involved in antenna miniaturization projects. Since 2006 he has been part-time connected to the Holst Centre, Eindhoven, The Netherlands and since 2009 he joined the Holst Centre as an employee of imec. Here he is working on wireless energy transfer for biomedical implants. In 2009 he obtained a Ph.D. from Eindhoven University of Technology, The Netherlands and Katholieke Universiteit Leuven, Belgium. He is part-time full professor at Eindhoven University of Technology where he teaches antenna theory. Hubregt is the author of the books ‘Array and Phased Array Antenna Basics’ (Wiley, 2005), ‘Approximate Antenna Analysis for CAD’ (Wiley, 2009) and `Antenna Theory and Applications’ (Wiley, 2012). Hubregt was co-organizer and co-chair of the 2019 IEEE Wireless Power Week in London, UK.
