Why the controversy over displacement currents never ends?
Masao Kitano
Displacement current is the last piece of the puzzle of electromagnetic theory. Its existence implies that electromagnetic disturbance can propagate at the speed of light and final…
Storage and retrieval of electromagnetic waves using electromagnetically induced transparency in a nonlinear metamaterial
Toshihiro Nakanishi, Masao Kitano
We investigate the storage and retrieval of electromagnetic waves using a nonlinear metamaterial, analogous to the electromagnetically induced transparency (EIT) observed in atomic…
Anisotropic Babinet-invertible metasurfaces to realize transmission-reflection switching for orthogonal polarizations of light
Yosuke Nakata, Yoshiro Urade, Kunio Okimura +4
The electromagnetic properties of an extremely thin metallic checkerboard drastically change from resonant reflection (transmission) to resonant transmission (reflection) when the…
Broadband and energy-concentrating terahertz coherent perfect absorber based on a self-complementary metasurface
Yoshiro Urade, Yosuke Nakata, Toshihiro Nakanishi +1
We demonstrate that a self-complementary checkerboard-like metasurface works as a broadband coherent perfect absorber (CPA) when symmetrically illuminated by two counter-propagatin…
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…
