Circular polarization measurement of γ-rays emitted from 32S(n,γ)33S reaction with polarized neutrons [PDF]

EPJ Web of Conferences
We aim to measure circular polarization of γ-rays emitted from neutron capture reactions with a pulsed neutron source for nuclear data and nuclear physics studies. A γ-ray polarimeter was developed to measure the circular polarization. One of performance

Chiral Dual-Core Photonic Crystal Fiber for an Efficient Circular Polarization Beam Splitter

Photonics, 2023
As a function of a circular polarization beam splitter (CPBS), combining a linear polarization beam splitter with a quarter-wave plate results in a polarization error in a circular polarization fiber-optic circuit.

Photonic Bandgaps of One-Dimensional Photonic Crystals Containing Anisotropic Chiral Metamaterials

Photonics, 2022
Conventional photonic bandgaps (PBGs) for linear polarization waves strongly depend on the incident angle. Usually, PBGs will shift toward short wavelengths (i.e., blue-shifted gaps) as the incident angle increases, which limits their applications.

Active Control of the THz Wave Polarization State by an Electronically Controlled Graphene Composite Metasurface

Frontiers in Physics, 2021
Active control of terahertz (THz) wave polarization state is of great significance for sensitive detection, imaging and communication. Here, a tunable THz quarter wave plate is designed by electronically controlling a composite metasurface consisting of ...

Circular Polarization Antenna-Filter

Advanced Electromagnetics, 2019
A two-function filtering antenna device in the 1-2 GHz band is investigated. The device radiates or receives electromagnetic waves of circular polarization and simultaneously performs the function of a second-order bandpass filter.

Circular Polarization near the Tight Focus of Linearly Polarized Light

Photonics, 2022
We have considered the tight focusing of light with linear polarization. Using the Richards–Wolf formalism, it is shown that before and after the focal plane, there are regions in which the polarization is circular (elliptical).

Polarization singularities in isotropic random vector waves [PDF]

, 2001
Following Nye & Hajnal, we explore the geometry of complex vector waves by regarding them as a field of polarization ellipses. Singularities of this field are the C lines and L lines, where the polarization is purely circular and purely linear ...
