  • Suwa, Tomomi; Tomita, Satoshi; Hosoito, Nobuyoshi; Yanagi, Hisao (MDPI AG, 2017-10-20)
    Herein we experimentally study magnetic multilayer metamaterials with broken translational symmetry. Epitaxially-grown iron-gold (Fe-Au) multilayers modulated using Fibonacci sequence—referred to as magnetic inverse ...
  • Tomita, Satoshi; Kurosawa, Hiroyuki; Ueda, Tetsuya; Sawada, Kei (IOP Publishing, 2018-02-06)
    This review introduces and overviews electromagnetism in structured metamaterials which undergo simultaneous time-reversal and space-inversion symmetry breaking due to magnetism and chirality. Direct experimental observation ...
  • Tomita, Satoshi; Sawada, Kei; Nagai, Shotaro; Sanada, Atsushi; Hisamoto, Nobuyuki; Ueda, Tetsuya (American Physical Society, 2017-10-13)
    This study observes microwave beam splitting dependent on circular polarizations through nonuniform chiral metamaterials. Nonuniform chiral metamaterials with a gradation in refractive index are constructed using chiral ...
  • Kodama, Toshiyuki; Kusanagi, Yusaku; Okamoto, Satoshi; Kikuchi, Nobuaki; Kitakami, Osamu; Tomita, Satoshi; Hosoito, Nobuyoshi; Yanagi, Hisao (American Physical Society, 2018-05-17)
    We investigate the microwave spectroscopies of a micrometer-sized single permalloy (Py) chiral structure on coplanar waveguides (CPWs). Under an external dc magnetic field applied in a direction perpendicular to the microwave ...
  • Hisamoto, Nobuyuki; Ueda, Tetsuya; Sawada, Kei; Tomita, Satoshi (American Physical Society, 2018-02-02)
    We experimentally observe asymmetric electromagnetic field profiles along two-dimensional chiral metamaterials. The asymmetric field profiles depending on the chirality and the operation frequency have been reproduced well ...
  • Matsui, Takahiro; Tomita, Satoshi; Asai, Motoki; Tadokoro, Yuzuru; Takano, Keisuke; Nakajima, Makoto; Hangyo, Masanori; Yanagi, Hisao (2016-02-18)
    Plasmonic chiral metasurfaces with pinwheel-like structures are fabricated on silver films using a focused ion-beam milling technique. In time-domain spectroscopy, we observe terahertz (THz) wave emission from metasurfaces ...
