Hidden Symmetry Protection and Topology in Surface Maxwell Waves
Yosuke Nakata, Toshihiro Nakanishi, Ryo Takahashi +2
Since the latter half of the 20th century, the use of metal in optics has become a promising plasmonics field for controlling light at a deep subwavelength scale. Surface plasmon p…
Broadband operation of active terahertz quarter-wave plate achieved with vanadium-dioxide-based metasurface switchable by current injection
Toshihiro Nakanishi, Yosuke Nakata, Yoshiro Urade +1
We demonstrate the broadband operation of a switchable terahertz quarter-wave plate achieved with an active metasurface employing vanadium dioxide. For this purpose, we utilize ani…
Optical heterodyne imaging of magnetostatic modes in one-dimensional magnonic crystals
Shotaro Z. Baba, Yosuke Nakata, Yoshitaka Ito +3
We demonstrate a real-space imaging of a heterodyne signal of light that is produced as a result of the Brillouin light scattering by coherently driven magnons in magnetostatic mod…
Helicity-Changing Brillouin Light Scattering by Magnons in a Ferromagnetic Crystal
R. Hisatomi, A. Noguchi, R. Yamazaki +4
Brillouin light scattering in ferromagnetic materials usually involves one magnon and two photons and their total angular momentum is conserved. Here, we experimentally demonstrate…
Topological Boundary Modes from Translational Deformations
Yosuke Nakata, Yoshitaka Ito, Yasunobu Nakamura +1
Localized states universally appear when a periodic potential is perturbed by defects or terminated at its surface. In this Letter, we theoretically and experimentally demonstrate…
Resonant magnetic induction tomography of a magnetized sphere
Arnaud Gloppe, Ryusuke Hisatomi, Yosuke Nakata +2
We demonstrate the structural imaging of magnetostatic spin-wave modes hosted in a millimeter-sized ferromagnetic sphere. Unlike for low-dimensional magnetic materials, there is no…
