Hedgehog subwavelength hole arrays: control over the THz enhanced transmission
(Institute of Physics Publishing, 2013)
Artículo / Artikulua,
By backing or sandwiching a holey metal layer with or between isotropic dielectric slabs, additional peaks of transmission within the long-wavelength regime arise as a result of the induced transverse magnetic (TM) or ...
Ultra-compact planoconcave zoned metallic lens based on the fishnet metamaterial
(AIP Publishing, 2013)
Artículo / Artikulua,
A 1.5λ0 -thick planoconcave zoned lens based on the fishnet metamaterial is demonstrated experimentally at millimeter wavelengths. The zoning technique applied allows a volume reduction of 60% compared to a full fishnet ...
Terahertz wave transmission in flexible polystyrene-lined hollow metallic waveguides for the 2.5-5 THz band
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A low-loss and low-dispersive optical-fiber-like hybrid HE11 mode is developed within a wide band in metallic hollow waveguides if their inner walls are coated with a thin dielectric layer. We investigate terahertz (THz) ...
Terahertz epsilon-near-zero graded-index lens
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
An epsilon-near-zero graded-index converging lens with planar
faces is proposed and analyzed. Each perfectly-electric conducting (PEC)
waveguide comprising the lens operates slightly above its cut-off frequency
and has ...
Frozen mode from hybridized extraordinary transmission and Fabry-Perot resonances
(American Physical Society, 2013)
info:eu-repo/semantics/article,
Frozen modes arising in stacked subwavelength hole arrays are studied in detail. Their origin is proved to be connected with the interaction between the extraordinary transmission resonance and the Fabry–Perot cavity mode. ...
Wideband unidirectional transmission with tunable sign-switchable refraction and deflection in nonsymmetric structures
(American Physical Society, 2013)
info:eu-repo/semantics/article,
A general theory of reciprocal unidirectional transmission with tunable sign-switchable refraction and deflection of outgoing wave in structures with broken spatial inversion symmetry is presented. Several coupling scenarios ...
