Nonbianisotropic complementary split ring resonators as angular selective metasurfaces
(Optical Society of America, 2017)
Artículo / Artikulua,
In this work, a metasurface with unconventional angular performance and composed by a nonbianisotropic complementary split ring resonator (NB-CSRR) is analyzed numerically and experimentally. A numerical study comparing ...
Annular apertures in metallic screens as extraordinary transmission and frequency selective surface structures
(IEEE, 2017)
Artículo / Artikulua,
A 2-D periodic array of annular apertures (or ring slots) is studied using an accurate circuit model. The model accounts for distributed and dynamic effects associated with the excitation of high-order modes operating above ...
Wideband backscattering reduction at terahertz using compound reflection grating
(Optical Society of America, 2017)
Artículo / Artikulua,
Backscattering reduction is usually achieved by using either absorbers or diffractions gratings at the expense of a narrow bandwidth. In this paper, we propose a different strategy based on a metallic compound reflection ...
One-way quasiplanar terahertz absorbers using nonstructured polar dielectric layers
(American Physical Society, 2017)
Artículo / Artikulua,
A concept of quasiplanar one-way transparent terahertz absorbers made of linear isotropic materials is presented. The resulting structure consists of a homogeneous absorbing layer of polar dielectric, GaAs, a dispersion-free ...
