Utsunomiya University · Shimizu Lab

Probing materials and circuits with radio waves.

We research high-frequency circuit technology and measurement/evaluation techniques related to next-generation wireless communication and next-generation autonomous driving. Passive circuit design in the microwave/millimeter-wave bands and high-frequency material measurement form the two pillars of our work — approaching the invisible behavior of electromagnetic fields from both the circuit and the sensing side.

About the Lab

Our lab belongs to the Information and Communication Systems Engineering field, within the Graduate School of Regional Development and Creativity / the Course of Information Electronics and Optics (Electrical & Electronic Engineering) of the Dept. of Engineering Fundamentals / the Dept. of Electrical and Electronic Engineering, Utsunomiya University, and is led by Assoc. Prof. Takashi Shimizu. We apply the many interesting properties of short-wavelength electromagnetic waves in the microwave-to-millimeter-wave/sub-THz range (roughly 1 GHz–300 GHz), with a focus on developing material characterization methods for the microwave, millimeter-wave and sub-THz bands, and on low-loss millimeter-wave/sub-THz passive circuit design. Some of our laboratory space and equipment is shared with Prof. Yoshinori Kogami's group.
