In our last blog, “Universities in Japan Granted with the YEP Award”, we announced the latest winners of the award. The YEP (Yes! Education Program) Award, an initiative run by our partners AET Japan, grants an extended one-year license to universities that use CST software, in order to assist their research projects. In this blog, Dr. Yasuaki Monnai from The University of Tokyo and winner of the YEP Award 2013, describes his recent research paper and details how he and his team use CST in their lab.
Winner’s comment (By Dr. Yasuaki Monnai from The University of Tokyo)
It is our great honor and pleasure that our recent paper [*] has been awarded for the YEP Award. In that paper, we presented a planar millimeter-wave antenna based on surface-wave scattering from a perturbed metal corrugation. The simulation of surface-waves is not quite compatible with a conventional transmission line model, so a direct calculation of Maxwell’s equations is important. Being based on the direct calculation along with realistic excitation ports and probes, we are allowed to model and investigate whatever strange structures on CST. We thus regard the CST as a virtual lab that allows us to not only prototype a new device but also predict how it is characterized. Consequently, new challenging ideas can be tested with a great speed at a low cost.
Our group has been working on the engineering of wide EM spectra ranging from MHz to THz for applications such as communication, sensing, and wireless power transmission with an emphasis on how they can be merged in human-computer interaction scenarios.
Irrespective of the spectra, we have been using CST for almost 10 years. CST serves also as the best tool for students to learn Maxwell’s equations as well as a common language when performing international collaborations. We believe CST is one of the first needs when starting up a new lab.
