Polarization-independent symmetrical digital metasurface absorber

open access: yesResults in Physics, 2021
A metasurface absorber developed using binary-coded unit cells and with the combination of coded unit cells resulted in excellent polarization insensitiveness, symmetrical characteristics, and tunable characteristics. As for binary patterns using the ‘0’

Distinguishing genuine entangled two-photon-polarization states from independently generated pairs of entangled photons [PDF]

open access: yes, 2004
A scheme to distinguish entangled two-photon-polarization states (ETP) from two independent entangled one-photon-polarization states (EOP) is proposed.

Design of a wideband random phase gradient metasurface by using line-shaped element

open access: yesJournal of Advanced Dielectrics, 2020
Based on phase randomization theory, a method for manufacturing metasurface with diffuse scatter performance is proposed. By using the line-shaped elements with random rotate angles and random distributing positions, the metasurface can achieve good ...

Top quark longitudinal polarization near the threshold in l+ l- annihilation [PDF]

open access: yes, 1998
We show that the longitudinal polarization of the top quarks produced in the annihilation of e+ e- or mu+ mu- into tbar t at energies near the threshold is not affected by the large Coulomb-type corrections, which greatly modify the total cross section ...

Polarization Independent Achromatic Meta-Lens Designed for the Terahertz Domain

open access: yesFrontiers in Physics, 2020
In recent years, metasurface-based focusing elements have gradually become an indispensable type of terahertz lenses. However, the meta-lens often suffers from chromatic aberration due to the intrinsic dispersion of each element, especially in the ...

One-Dimensionally Polarization-Independent Retrodirective Metasurface [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2019
A one-dimensionally polarization-independent retrodirective metasurface (PIRMS) is proposed in this letter. The retrodirective metasurface (RMS) consists of ring structures on its ground plane to achieve the polarization-independent characteristics.

Incident-angle-insensitive and polarization independent polarization rotator

open access: yesOptics Express, 2010
This paper proposes a method to design an incident-angle-insensitive polarization-independent polarization rotator. This polarization rotator is composed of layers of impedance-matched anisotropic metamaterial (IMAM) with each layer's optical axes gradually rotating an angle.
