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…
Reconfigurable terahertz quarter-wave plate for helicity switching based on Babinet inversion of anisotropic checkerboard metasurface
Yosuke Nakata, Kai Fukawa, Toshihiro Nakanishi +3
Dynamic helicity switching by utilizing metasurfaces is challenging because it requires deep modulation of polarization states. To realize such helicity switching, this paper propo…
Energy loss of terahertz electromagnetic waves by nano-sized connections in near-self-complementary metallic checkerboard patterns
Keisuke Takano, Yoku Tanaka, Gabriel Moreno +9
The design of a self-complementary metallic checkerboard pattern achieves broadband, dispersion-less, and maximized absorption, concentrating in the deep subwavelength resistive co…
Freestanding transparent terahertz half-wave plate using subwavelength cut-wire pairs
Yosuke Nakata, Yudai Taira, Toshihiro Nakanishi +1
We designed a cut-wire-pair metasurface that works as a transparent terahertz half-wave plate, by matching the electric and magnetic resonances of the structure. Due to the impedan…
Supersymmetric correspondence in spectra on a graph and its line graph: From circuit theory to spoof plasmons on metallic lattices
Yosuke Nakata, Yoshiro Urade, Toshihiro Nakanishi +3
We investigate the supersymmetry (SUSY) structures for inductor-capacitor circuit networks on a simple regular graph and its line graph. We show that their eigenspectra must coinci…
