Ultra-Broadband Communication Infrastructure Lab
Machine-translated · View original
A lab that researches electronic devices for millimeter waves and terahertz waves, and their applications to communication.
AboutAbout the lab
Creating new electronic devices for millimeter waves and terahertz waves.
The Ultra-Broadband Communication Infrastructure Lab conducts research to pioneer and put into practical use technologies for millimeter waves and terahertz waves (sub-millimeter waves), an electromagnetic wave region whose technology is still under development.
The lab creates new electronic devices and circuit systems that operate in this region, and carries out research and development on applying them to information and communication systems and measurement systems.
The lab consists of the Ultra-Broadband Device Physics research field led by Professor Sato and the Ultra-Broadband Quantum Electronics research field led by Associate Professor Lin.
It belongs to the Information and Communication Infrastructure Division of the Research Institute of Electrical Communication.
Key terms
- Terahertz waves
