Diodelike asymmetric transmission of linearly polarized waves using magnetoelectric coupling and electromagnetic wave tunneling
(American Physical Society, 2012-05-24)An asymmetric, reciprocal, diffraction-free transmission of linearly polarized waves in a new diodelike, three-layer, ultrathin, chiral structure is studied theoretically and experimentally. The exploited physical mechanism ... -
Dipole antenna couplers for subwavelength metal-insulator-metal waveguides
(Optical Society of America, 2010)Near-infrared light (λ=1550 nm) was coupled into a 100-nm-core Ag/SiO2/Ag waveguide using dipole antennas. We demonstrate that using antennas, the field intensity inside the waveguide can be enhanced by changing the antenna ... -
Experimental verification of metamaterial based subwavelength microwave absorbers
(American Institute of Physics, 2010-10-29)We designed, implemented, and experimentally characterized electrically thin microwave absorbers by using the metamaterial concept. The absorbers consist of (i) a metal back plate and an artificial magnetic material layer; ... -
Nanoantenna couplers for metal-insulator-metal waveguide interconnects
(SPIE, 2010)State-of-the-art copper interconnects suffer from increasing spatial power dissipation due to chip downscaling and RC delays reducing operation bandwidth. Wide bandwidth, minimized Ohmic loss, deep sub-wavelength confinement ... -
Non-ideal cloaking based on Fabry-Perot resonances in single-layer high-index dielectric shells
(Optical Society of American (OSA), 2009)Strong reduction of the scattering cross section is obtained for subwavelength dielectric and conducting cylinders without any magnetism for both TE and TM polarizations. The suggested approach is based on the use of ... -
Optically thin composite resonant absorber at the near-infrared band: A polarization independent and spectrally broadband configuration
(Optical Society of American (OSA), 2011)We designed, fabricated, and experimentally characterized thin absorbers utilizing both electrical and magnetic impedance matching at the near-infrared regime. The absorbers consist of four main layers: a metal back plate, ... -
Raman enhancement on a broadband meta-surface
(American Chemical Society, 2012-07-30)Plasmonic metamaterials allow confinement of light to deep subwavelength dimensions, while allowing for the tailoring of dispersion and electromagnetic mode density to enhance specific photonic properties. Optical resonances ... -
Single and cascaded, magnetically controllable metasurfaces as terahertz filters
(Optical Society of America OSA, 2016)Transmission of a normally incident, linearly polarized, plane wave through either a single electrically thin metasurface comprising H-shaped subwavelength resonating elements made of magnetostatically controllable InAs ...
