Weak measurements with completely mixed probe states
Shuhei Tamate, Toshihiro Nakanishi, Masao Kitano
Weak measurements with mixed probe states were investigated in the presence of noise in the probe system. We show that the completely mixed state can be used as a probe state for w…
Observation of flat band for terahertz spoof plasmon in metallic kagomé lattice
Yosuke Nakata, Takanori Okada, Toshihiro Nakanishi +1
We study the dispersion relation of a metamaterial composed of metallic disks and bars arranged to have kagome symmetry and find that a plasmonic flat band is formed by the topolog…
Efficient second harmonic generation in a metamaterial with two resonant modes coupled through two varactor diodes
Toshihiro Nakanishi, Yasuhiro Tamayama, Masao Kitano
We present an effective method to generate second harmonic (SH) waves using nonlinear metamaterial composed of coupled split ring resonators (CSRRs) with varactor (variable capacit…
