Research Content
At The University of Tokyo, I was a member of three laboratories.
I studied bilayer graphene at two of the three laboratories: in the first laboratory, I studied the changes in physical states of bilayer graphene with a twisted stacking structure; and in the second laboratory, I studied the changes in stacking structure of bilayer graphene due to the intercalation and desorption of ions (R. Akiyama, Y. Takano, et. al., Appl. Phys. Lett. 110, 233106 (2017)).
In the remaining one laboratory, I studied metamaterials: fabrication of THz filters using a 3D printer and a harmonic generation focusing metalens using electron beam lithography.

At Osaka University, I studied metamaterials and transformation electromagnetics. Basically, I designed various media based on transformation electromagnetics and studied how to realize the designed media by using metamaterials. For example, I studied invisibility cloaks (Y. Takano and A. Sanada, EPJ Appl. Metamat. 7, 4 (2020)), dual imaging media (Y. Takano and A. Sanada, IEEE Trans. Microw. Theory Techn. 69, 3616 (2021)), and dual-band media (Y. Takano and A. Sanada, Phys. Rev. B 104, 165115 (2021)). As another approach to realize invisibility cloaks, I also studied the realization by using near-zero index medium (Y. Takano, and A. Sanada, IEEE Trans. Microw. Theory Techn. 66, 3921 (2018)).
