Negative refractive index metamaterial with high transmission, low reflection, and low loss in the terahertz waveband.
TL;DR: Measurements by terahertz time-domain spectroscopy demonstrate a metamaterial with a negative refractive index n of -4.2 + j0.17, high transmitted power of 81.5%, low reflected power of 4.3%, and a high figure of merit of 24.2 at 0.42 THz.
Journal ArticleDOI
Metamaterial Demonstrates Both a High Refractive Index and Extremely Low Reflection in the 0.3-THz Band
Koki Ishihara,Takehito Suzuki +1 more
TL;DR: In this article, the authors demonstrate a metamaterial with both a high refractive index and extremely low reflection consisting of symmetrically aligned paired cut metal wires with 18,800 units on the front and back surfaces of a dielectric substrate.
Journal ArticleDOI
Terahertz laminated-structure polarizer with high extinction ratio and transmission power
TL;DR: In this article, a terahertz polarizer consisting of a laminated metal-slit array on a polymer film is presented, and the iterative design is efficiently performed with a mode-matching method.
Journal ArticleDOI
Extreme-sensitivity terahertz polarizer inspired by an anisotropic cut-through metamaterial.
TL;DR: An anisotropic cut-through metal-slit array is demonstrated for an ideal terahertz polarizer with a high extinction ratio and transmission power and shed light on a variety of path-breaking applications including single-photon detection and quantum information and communication at lower frequencies.
Journal ArticleDOI
Achromatic wave plate in THz frequency region based on parallel metal plate waveguides with a pillar array
Masaya Nagai,Noriyuki Mukai,Yosuke Minowa,Masaaki Ashida,Takehito Suzuki,Jun Takayanagi,Hideyuki Ohtake +6 more
TL;DR: An achromatic wave plate based on parallel metal plate waveguides in the high THz frequency region is demonstrated and a numerical simulation showed that the height of the periodic roughness is important for optimizing the birefringence.
