Shohei Kidera, Professor
0 student voices
The Kidera Lab studies sensing technologies that use electromagnetic waves (microwaves, millimeter waves, and terahertz waves) to examine the interior of objects and what lies behind obstacles. These waves can penetrate to depths ranging from several tens of centimeters to a few millimeters, so they are said to enable measurement even where lasers or cameras cannot see. The lab combines physical insight from analyzing electromagnetic scattering with data science such as signal and image analysis and machine learning. The lab cites applications such as detecting people out of line of sight in autonomous driving, nondestructive measurement of roads and tunnels, and medical imaging diagnosis of cancer tissue using dielectric properties.

Kun Li, Associate Professor
0 student voices
The Li Lab studies foundational technologies for next-generation wireless communication and the safety of human exposure to radio waves. Its main themes are evaluating the antennas of wireless terminals such as mobile phones, evaluating the effects of radio waves on the human body, and understanding the wireless environment inside tunnels. The lab aims to achieve both ultra-high-speed, highly reliable communication and safe use of radio waves. The lab belongs to the Advanced Wireless & Communication Research Center and was established in April 2023.

Yasutaka Murakami, Assistant Professor
0 student voices
The Murakami Lab researches solutions to electromagnetic communication environment problems in 5G/B5G using metamaterial and antenna technologies. The lab works on research that contributes to the advancement of next-generation high-speed wireless communication. The lab conducts joint research with the Electromagnetic Compatibility Laboratory of the National Institute of Information and Communications Technology (NICT).

Takuo Tsuda, Associate Professor
0 student voices
The Tsuda Lab conducts research that explores the Earth and space through remote sensing using light and radio waves. Established in February 2015, the lab works on research including compact digital cameras, Himawari satellite image analysis, Arctic spectrographs, Antarctic lidar, and Arctic lidar. The lab also carries out joint research with nearby labs on campus and with educational and research institutions outside the university. On the lab's website, it is introduced under the name "Tsuda-ken."

Takeyoshi Tajiri, Associate Professor
0 student voices
The Tajiri Lab conducts experimental research aimed at applying materials centered on nitride semiconductors to electronic and optical devices. Covering everything from growing crystals to semiconductor processing and the evaluation of electrical and optical properties, the lab develops new nanoscale fabrication and measurement techniques as well as new devices. Undergraduate thesis students are taught experimental methods from scratch, so no prior knowledge of semiconductors is needed. However, a prior interview is required to be assigned to the lab for graduation research, and students are advised to first email a faculty member to make an appointment.

Xiao Xiao, Professor
0 student voices
The Xiao Lab studies the electromagnetic environment and EMC (Electromagnetic Compatibility), the electrical counterpart of environmental problems, as well as electromagnetic field visualization, microwave and millimeter-wave transmission circuits, and computational electromagnetics. The lab works on methods for measuring and evaluating electromagnetic fields near circuit boards, analysis of crosstalk between transmission lines, and numerical methods for electromagnetic fields. The lab is very active in joint research with companies and has many international exchanges. The lab carries out its research in collaboration with the Kayano Lab.

Yasuhide Hobara, Professor
0 student voices
The Hobara Lab focuses on observing various electromagnetic phenomena and studies the electromagnetic environment of Earth and space through both experiments and theory. Using observational data from a range of frequency bands, the lab conducts basic research on monitoring and predicting disturbances in space, extreme weather such as torrential rain, typhoons, and tornadoes, natural disasters such as earthquakes, and climate change. The lab aims to help reduce natural disasters and contribute to building a resilient society. The lab strives to provide opportunities such as presenting at international conferences, interacting with visiting researchers and international students from abroad, and being sent overseas for short-term joint research.

Hiroshi Kikuchi, Associate Professor
0 student voices
The Kikuchi Lab centers on developing remote sensing technology for meteorological phenomena, and researches the development of next-generation weather radar and the analysis of observation data on cumulonimbus clouds. The lab focuses on phased array radar, which can observe in fine detail up to high altitudes at short time intervals, and aims to contribute to the prevention of weather-related disasters. The lab also works on developing an observation system that pinpoints the positions of lightning discharges in three dimensions. The lab conducts its research together with the members of the Center for Space and Electromagnetic Environment Research.

Yoshiki Kayano, Professor
0 student voices
The Kayano Lab studies electromagnetic compatibility (EMC), the discipline of enabling electronic devices to coexist and operate in complex electromagnetic environments. Devices that use high-frequency electrical signals, such as computers, can radiate unwanted electromagnetic waves and interfere with other devices. Working closely with the Xiao Lab in the same EMC field, the lab investigates how high-frequency signals propagate and how unwanted electromagnetic waves are generated, through both experiments and simulation. The lab treats EMC problems on and around printed circuit boards as fundamental research, using simplified models to clarify the basic phenomena.

Kazuki Nishi, Associate Professor
0 student voices
The Nishi Lab studies the theory and algorithms of signal processing, which extract target information from signals obtained from images, audio, and various measurements. Currently, the lab focuses on methods for testing camera performance and quality, and develops techniques for measuring vibration, resolution, and more. Its research themes are vibration measurement of tripods and shutters, precise resolution measurement, and measurement of camera optical axis distortion. Some of these techniques have already been put to practical use, and the lab aims to develop technology that people actually use.
