A Novel Reconfigurable Metasurface with Coincident and Ultra-Wideband LTL and LTC Polarization Conversion Functions [PDF]

open access: yesRadioengineering, 2019
In this paper, a novel reconfigurable metasurface (NRM) with coincident and ultra-wideband linear-to-linear (LTL) and linear-to-circular (LTC) polarization conversion functions is proposed. The unit of the proposed NRM consists of superstrate, air layer,

Ultra-Thin Metasheet for Dual-Wide-Band Linear to Circular Polarization Conversion With Wide-Angle Performance

open access: yesIEEE Access, 2020
Satellite communication systems require dual-band circularly polarized (CP) waves to integrate receiving and transmit antennas into one dual-band terminal. Polarization converters play an important role in such a scenario to convert the incoming linearly

Anomalous polarization conversion in arrays of ultrathin ferromagnetic nanowires

open access: yes, 2015
We study optical properties of arrays of ultrathin nanowires by means of the Brillouin scattering of light on magnons. We employ the Stokes/anti-Stokes scattering asymmetry to probe the circular polarization of a local electric field induced inside ...

Generation of hybrid polarization-orbital angular momentum entangled states

open access: yes, 2010
Hybrid entangled states exhibit entanglement between different degrees of freedom of a particle pair and thus could be useful for asymmetric optical quantum network where the communication channels are characterized by different properties. We report the

Polarization-controlled multifunctional polarization conversion in bilayer chiral metamaterials

open access: yes, 2022
Abstract In this paper, a chiral metamaterial (MM) structure composed of bilayer twisted split-ring resonator (SRR) arrays is proposed and demonstrated to realize polarization-controlled, dual-directional, and multifunctional polarization conversion for terahertz (THz) waves.

Reconfigurable Multifunctional Metasurface for Broadband Polarization Conversion and Perfect Absorption

open access: yesIEEE Access, 2020
A reconfigurable multifunctional metasurface is proposed to realize the switching between broadband polarization conversion and perfect absorption by integrating the PIN diodes into the structure. An appropriate feed plate is designed to provide the bias

Remote polarization entanglement generation by local dephasing and frequency upconversion

open access: yes, 2017
We introduce a scheme for remote entanglement generation for the photon polarization. The technique is based on transferring the initial frequency correlations to specific polarization-frequency correlations by local dephasing and their subsequent ...

Interference and complementarity for two-photon hybrid entangled states

open access: yes, 2010
In this work we generate two-photon hybrid entangled states (HES), where the polarization of one photon is entangled with the transverse spatial degree of freedom of the second photon.

Linear-to-Circular Polarization Conversion Using Metasurface

open access: yesIEEE Transactions on Antennas and Propagation, 2013
A metasurface (MS) used to convert the linearly polarized (LP) signal from a source antenna into a circularly polarized (CP) signal is proposed and studied. The MS consists of 16 unit cells arranged in a 4 × 4 layout. Each unit cell is a rectangular loop with a diagonal microstrip.
