Associate Professer / SASAKI Tomoyuki
Associate Professer Sasaki is easy to approach and gives clear advice whenever we have questions. He often points us to useful papers and resources, which really helps our research. He also shares unexpected and funny stories from time to time, making the lab atmosphere open, relaxed, and motivating.

Research Content

In our laboratory, we study terahertz (THz) waves (0.1–10 THz) and how to control them. THz waves are attracting attention for future communication, imaging, and sensing technologies. We design and build THz devices using laser micromachining, sub-femtosecond pulse jet printing, and liquid-crystal materials. We also work on metamaterial-based structures to improve wave control. Our goal is to connect material design with practical devices that can be used in real applications.

A Day in the Lab

Our lab has a friendly vibe. Seniors are easy to talk to, so when we’re stuck, we can just ask and get helpful advice. Except for weekly report meetings, everyone usually works on their own research at their own pace and timing. That independence is one of the nice parts of this lab. Even when people are focused, no one acts annoyed if you ask, “Can I ask you something?” Questions and short discussions happen naturally, which makes the lab comfortable for both study and communication.
