Plasmonic Resonators

Masanobu Iwanaga graduated from Kyoto University, Japan, in 1998 and received his doctorate from the same university in 2003. Since then, he was an assistant professor at the Department of Physics, Tohoku University. Now, he is affiliated to the National Institute for Materials Science (NIMS), Japan, which he joined in 2009.
