An Assessment of Simulated Compact Polarimetric SAR Data for Wetland Classification Using Random Forest Algorithm

Canadian Journal of Remote Sensing, 2017
Synthetic aperture radar (SAR) compact polarimetry (CP) systems are of great interest for large area monitoring because of their ability to acquire data in a wider swath compared to full polarimetry (FP) systems and a significant improvement in ...

A compact and robust method for full Stokes spectropolarimetry

, 2012
We present an approach to spectropolarimetry which requires neither moving parts nor time dependent modulation, and which offers the prospect of achieving high sensitivity. The technique applies equally well, in principle, in the optical, UV or IR.

Role of Coherence in Polarization Response of Hybrid Monolayer MoS2‐Gold Nanoparticle Systems

Advanced Physics Research, Volume 5, Issue 1, January 2026.
Monolayer transition metal dichalcogenides (1L‐TMDs) exhibit strong second‐order susceptibility and symmetry‐driven selection rules due to their threefold lattice symmetry. This study examines the far‐field circular polarization properties of second harmonic generation (SHG) from MoS2 monolayers interacting with gold nanoparticles.

Using the CLEAN Method in Three-Dimensional Polarimetric ISAR Imaging Based on Volumetric Scattering Points [PDF]

Journal of Electromagnetic Engineering and Science
We developed a new technique for generating three-dimensional monostatic inverse synthetic aperture radar (ISAR) images using various types of polarimetric information on targets.

Structure‐Response Relationships in Rigid C2‐Symmetric Excitonic Systems: Principles, Modulation, and Functional Design Strategies

ChemPhysChem, Volume 27, Issue 2, January 2026.
Rigid C2‐symmetric chromophores reveal how transition dipole orientation, magnitude, and conformational locking govern exciton coupling and g‐factor amplification, providing a structural blueprint for the rational design of advanced chiroptical molecular and material architectures.

Polarimetry of cosmic gamma-ray sources above e+e- pair creation threshold

, 2013
We examine the potential for gamma-ray conversion to electron-positron pairs, either in the field of a nucleus or of an electron of a detector, to measure the fraction P of linear polarization of cosmic gamma sources.

Perspectives on Systematic Cloud Microphysics Scheme Development With Machine Learning

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Cloud microphysics—the collection of processes that govern the small‐scale formation, evolution, and interactions of liquid droplets and ice crystals in clouds and precipitation—remains a major source of uncertainty in weather and climate models.

Compton Polarimetry

, 2022
Photons preferentially Compton scatter perpendicular to the plane of polarisation. This property can be exploited to design instruments to measure the linear polarisation of hard X-rays ($\sim$10 - 100 keV). Photons may undergo two interactions in the sensitive volume of the instrument, i.e. a scattering followed by an absorption.

Arbitrary polarization control with a segmented APPLE‐II undulator

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 73-83, January 2026.
A four‐segmented APPLE‐II undulator was constructed, and its operation has started at NanoTerasu BL13U. The performance of arbitrary polarization control using phase shifters is demonstrated.A newly developed four‐segmented APPLE‐II undulator enables arbitrary polarization control in the soft to tender X‐ray region.

Polarimeters for the Detection of Anisotropy from Reflectance

Micromachines
Polarimetry is used to determine the Stokes parameters of a laser beam. Once all four S0,1,2,3 parameters are determined, the state of polarisation is established.
