Winner’s comments
Dr. Masayuki Fujita
We are happy and greatly honored to receive the YEP Award
for our recent paper [*]. In this paper, we demonstrated the manipulation of a
terahertz electromagnetic wave by a photonic crystal. Terahertz waves have
unrealized technological potential and the frequencies are located between
radio and light waves. Research on terahertz waves is interdisciplinary and has
attracted much attention for potential applications in a wide variety of
fields, including photonics, optical science, material science, medicine,
biology, chemistry, and information communication technology. However, a lack
of efficient manipulation technology for terahertz waves has thus far hindered
the development of smart and compact components that would make new
applications possible. As a potential route towards such a technology platform,
we presented a novel concept that involves the trapping and capture of incident
terahertz waves by the in-plane resonance of a silicon photonic-crystal slab
consisting of periodic microstructures on a scale comparable to the wavelengths
of interest. In order to design the photonic crystal, electromagnetic
simulations are very important. CST Microwave Studio is powerful tool for
creating simulations. Our Information Photonics Group at Osaka University is
developing state-of-the-art terahertz-wave devices and systems towards future
advanced applications.

We are delighted that our paper[*] has been chosen for YEP Award 2014.
In this paper, we presented a waffled waveguide as a beam scanning antenna for wireless optical communication. Optical devices like our antenna are very large compared to the wavelength and it takes enormous time to analyze. CST MW Studio fixes this problem. Our group has been working on
antennas engineering not only optical antenna but also RF antennas such as base station antenna and super gain antenna. CST has large presence for these studies as well. We believe CST contributes to the development of antenna technology.
