In the future ubiquitous informational society, information-processing communication systems should be human- and environment-friendly in such a way that they allow anyone to access any desired information, any time, anywhere, easily and immediately at ultra-low energy consumption and without causing any serious environmental problems.
The objective of this Research Group is to create human- and environment-friendly information processing and communication systems by exploiting quantum devices and novel circuits and system architectures. Efforts are being made to design and characterize millimeter-wave/THz-wave circuits incorporating ultrafast quantum devices, electromagnetic periodic structures, and artificial meta-materials. The application of these circuits to wireless communication and optical communication systems is also being investigated.
