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…
Classical realization of dispersion-canceled, artifact-free, and background-free optical coherence tomography
Kazuhisa Ogawa, Masao Kitano
Quantum-optical coherence tomography (Q-OCT) provides a dispersion-canceled axial-imaging method, but its practical use is limited by the weakness of the light source and by artifa…
Observation of a nonradiative flat band for spoof surface plasmons in a metallic Lieb lattice
Sho Kajiwara, Yoshiro Urade, Yosuke Nakata +2
We demonstrate a nonradiative flat band for spoof surface plasmon polaritons bounded on a structured surface with Lieb lattice symmetry in the terahertz regime. First, we theoretic…
