Asymmetric chiral metamaterial circular polarizer based on four U-shaped split ring resonators
(Optical Society of America, 2011-04-28)An asymmetric chiral metamaterial structure is constructed by using four double-layered U-shaped split ring resonators, which are each rotated by 90° with respect to their neighbors. The peculiarity of the suggested design ... -
Asymmetric Fabry-Perot-type transmission in photonic-crystal gratings with one-sided corrugations at a two-way coupling
(American Physical Society, 2012-11-29)Strongly asymmetric Fabry-Perot-type transmission arising at the two-way coupling has been studied in the case of normal incidence for slabs of two-dimensional photonic crystals (PCs) with one-sided corrugations that are ... -
Asymmetric transmission in prisms using structures and materials with isotropic-type dispersion
(Optical Society of America, 2015)It is demonstrated that strong asymmetry in transmission can be obtained at the Gaussian beam illumination for a single prism based on a photonic crystal (PhC) with isotropic-type dispersion, as well as for its analog made ... -
Asymmetric transmission of linearly polarized waves and polarization angle dependent wave rotation using a chiral metamaterial
(Optical Society of America, 2011-07-18)An electrically thin chiral metamaterial structure composed of four U-shaped split ring resonator pairs is utilized in order to realize polarization rotation that is dependent on the polarization of the incident wave at ... -
Asymmetric transmission of terahertz waves using polar dielectrics
(Optical Society of America, 2014-02-10)Asymmetric wave transmission is a Lorentz reciprocal phenomenon, which can appear in the structures with broken symmetry. It may enable high forward-to-backward transmittance contrast, while transmission for one of the two ... -
Broadband mixing of PT-symmetric and PT-broken phases in photonic heterostructures with a one-dimensional loss/gain bilayer
(Nature Publishing Group, 2017)Combining loss and gain components in one photonic heterostructure opens a new route to efficient manipulation by radiation, transmission, absorption, and scattering of electromagnetic waves. Therefore, loss/gain structures ... -
Characteristic attributes of multiple cascaded terahertz metasurfaces with magnetically tunable subwavelength resonators
(Wiley-VCH Verlag, 2018)The characteristics of multiple cascaded metasurfaces comprising H-shaped, magnetostatically controllable, subwavelength terahertz (THz) resonators made of InAs were systematically investigated, using a commercial solver ... -
Connection of collimation, asymmetric beaming, and independent transmission-reflection processes in concentric-groove gratings supporting spoof surface plasmons
(Springer, 2019)Transmission through subwavelength apertures enables separation of the incidence half-space and the exit half-space, which leads to that the spatial distribution of the field in the latter is not affected by the distribution ... -
Defect-mode-like transmission and localization of light in photonic crystals without defects
(The American Physical Society, 2010-10-29)It is shown that far- and near-field effects, which are similar to those arising in transmission through finite-thickness photonic crystals (PCs) with structural defects, can be obtained in the conventional defect-free ... -
Dielectric inspired scaling of polarization conversion subwavelength resonances in open ultrathin chiral structures
(A I P Publishing LLC, 2015)It is shown that the scaling of subwavelength resonances in open ultrathin chiral structures can be obtained by varying only the permittivity of dielectric spacers, while multiband one-way polarization conversion and related ... -
Diffraction inspired unidirectional and bidirectional beam splitting in defect-containing photonic structures without interface corrugations
