So far, gyromagnetic property of ferrite have played important role in microwave devices such as circulators, isolators but we have issues of incompatibility to integrated circuit and requirement of static magnetic bias field. The gyrotropic provides “non-reciprocity” for wave propagation and it is originated from unidirectional motion of spin. In my talk, creation of artificial gyromagnetism by combination of transistor and electromagnetic structure and its application will be presented.
Toshiro Kodera received a Dr. Eng. from Kyoto Institute of Technology in 2001. He went on to join Osaka Institute of Technology, and in 2005 he joined ATR International Kyoto, where he engaged in R&D of 60GHz GaAs MMIC. In 2008, he joined École Polytechnique of Montréal, where he developed unique microwave devices. Since 2014, he has been an Associate Professor of Meisei University, Tokyo. Dr. Kodera has received several academic awards and is a senior member of IEEE.
