- TUAT Embarking on the discovery of "Suzuki's Law" for terahertz wave control -
Takehito Suzuki of the National University Corporation Tokyo University of Agriculture and Technology Graduate School Graduate School of Engineering Department of Electrical Engineering and Computer Science Associate Professor Institute of Engineering Division of Advanced Electrical and Electronics Engineering, Mahiro Ochiai (2nd year master's course), Yuta Tanaka (1st year master's course), Faculty of Engineering Department of Electrical Engineering and Computer Science Riku Torii (4th year) and Taiyo Shiobara (4th year) of the same university have developed the next-generation communication system "6G (Beyond 5G)" (5G), which is expected to be used in the 1st century, and has embarked on the discovery of "Suzuki's Law," which describes the generality of the relationship between material properties and structure.
The research group has accumulated a huge amount of data (big data) through experiments and analyses on functional materials. However, the physical phenomena of functional materials are not fully explained. It takes genius intuition and a huge amount of time for humans to discover new laws of physics. Therefore, this research team used AI for Science through the collaboration between humans and AI. AI for Science is a method that has the potential to reach hidden laws faster than it takes for humans to discover new laws of physics. It is expected to contribute greatly to the discovery and application of new physical laws and the construction of new academic fields.
The results of this research were presented at the 86th Autumn Meeting of the Japan Society of Applied Physics on September 8, 2025.

Research background
Terahertz waves, which are in a higher frequency band than the currently widespread 5G communications, are expected to be used in the next generation of high-speed wireless communications, enabling high-speed, high-capacity communications. In 2017, this research group discovered a unique functional material aimed at freely controlling electromagnetic waves in the terahertz wave band. Since then, they have accumulated a huge amount of data (big data) through experiments and analyses of various functional materials that control terahertz waves. However, no laws have yet been discovered that can fully explain the physical phenomena that occur in these functional materials.
Research Structure
This research was conducted by Takehito Suzuki of Tokyo University of Agriculture and Technology Graduate School Institute of Engineering Division of Advanced Electrical and Electronics Engineering, Associate Professor of the Graduate School of Graduate School of Engineering Department of Electrical Engineering and Computer Science Mahiro Ochiai (2nd year master's program), Yuta Tanaka (1st year master's program), and Faculty of Engineering Department of Electrical Engineering and Computer Science Riku Torii (4th year) and Taiyo Shiobara (4th year). This research was partially supported by the Japan Society for Japan the Promotion of Science (JSPS) Grants-in-Aid for Scientific Research (B) (24K01376), the Japan Science and Technology Agency (JST) Emergent Research Support Project (JPMJFR222I), and the Challenging Research (Germination) (24K21617).
Research results and future developments
This research group reported on an early version of "Suzuki's Law," which attempted to link the structure of a uniquely developed functional material with indices important for controlling electromagnetic waves, such as the "real part of the refractive index" and the "real part of the specific impedance." AI for Science was used to describe big data on experimental and analytical results for functional materials in a simple physical model. Going forward, the group aims to complete "Suzuki's Law," a general solution for the material properties of functional materials, with the aim of achieving disruptive innovation through AI for Science and functional materials.
