Title: The State-of-the-art Research on Gap Waveguide Technology at Chalmers with ERC project Gapwave ICs

Speaker: Prof. Jian Yang, Antenna Systems Group, Dept. of  Electrical Engineering, Chalmers Univ. of Technology.
Gap waveguide technology was invented by Prof. Kildal in 2008. The main contribution from this invention is to make the manufacture of devices and antennas with separate plates without requiring the difficult conductive connection between the top and the bottom plates at millimeter waves and THz regime. The theory behind this possibility is to create a wave stop in a gap between a PEC plate and a PMC plate realized with texture structure. This technology is a disruptive one, which disrupts conventional rectangular waveguides, microstrip line, existing packaging, diffusion bonding, dip brazing and wire-bonding for MMIC, etc. at mm-waves and THz-waves.
This seminar reviews the state of the art and the recent developments of the gap waveguide technology at Chalmers University of Technology funded with ERC Advanced grant Gapwave ICs, collaborated with Gapwaves AB. Several examples of high gain planar antennas will be included in the presentation. Further developments of Per-Simon’s invention, such as half-height pin gap waveguide, will be also discussed. Examples of applications of the gap waveguide technologyshows the potentials for the technology to solve problems in mmWaves.

Jian Yang received the B.Sc. degree in electrical engineering from the Nanjing University of Science and Technology, Nanjing, China, in 1982, the M.Sc. degree in electrical engineering from the Nanjing Research Center of Electronic Engineering, Nanjing, in 1985, and the Swedish Licentiate and Ph.D. degrees from Chalmers University of Technology, Gothenberg, Sweden, in 1998 and 2001, respectively. From 1985 to 1996, he was with the Nanjing Research Institute of Electronics Technology, Nanjing, China, as a Senior Engineer. From 1999 to 2005, he was with the Department of Electromagnetics, Chalmers University of Technology, Gothenberg, Sweden, as a Research Engineer. During 2005 and 2006, he was with COMHAT AB as a Senior Engineer. From 2006 to 2010, he was an Assistant Professor, from 2010 to 2016, he was an Associate Professor, and since 2016 he has been a professor with the Department of Signals and Systems, Chalmers University of Technology. His research interests include 60-140GHz antennas, terahertz antennas, MIMO antennas, ultrawideband (UWB) antennas and UWB feeds for reflector antennas, UWB radar systems, UWB antennas in near-field sensing applications, hat-fed antennas, reflector antennas, radome design, and computational electromagnetics.
