Urban Tomographic Imaging Using Polarimetric SAR Data

Remote Sensing, 2019
In this paper, we investigate the potential of polarimetric Synthetic Aperture Radar (SAR) tomography (Pol-TomoSAR) in urban applications. TomoSAR exploits the amplitude and phase of the received data and offers the possibility to resolve multiple ...

Thermoplasmonic‐Controlled Optical Filters Based on the Combination of Chiral Liquid Crystals and Metasurfaces

Macromolecular Rapid Communications, EarlyView.
A broadband cholesteric liquid crystal (CLC) combined with a bottom‐up metasurface absorber enables the realisation of thermoplasmonic‐controlled optical filters. These filters combine a CLC reflector for visible light with a metasurface absorber operating in the near‐infrared (NIR) range.

Multimodal fluorescence microscope with fast adaptive polarimetry

HardwareX, 2023
Polarized light microscopy is a widely used technique to observe specimens that are optically anisotropic, or birefringent. It has a broad applicability in the study of minerals, soft materials such as polymers, complex fluids or liquid crystals, and ...

Polarímetro virtual: desenvolvimento, utilização e avaliação de um software educacional

Química Nova, 2012
Optical activity is the ability of chiral substances to rotate the plane of plane-polarized light and is measured using an instrument called a polarimeter.

Population dynamics of stubby root nematodes (Trichodorus and Paratrichodorus spp.) associated with ‘Docking disorder’ of sugar beet (Beta vulgaris L.), in field rotations with cover crops in East England

Annals of Applied Biology, EarlyView.
This study evaluated the population dynamics of stubby root nematodes (SRN) in field rotations with cover crops and the subsequent effect of this rotation on sugar beet quality and quantity attributes. It was clear that the SRN densities under field conditions are influenced by multiple factors, such as the type of cover crops grown, soil disturbance ...

Ultraviolet Polarimetry [PDF]

International Astronomical Union Colloquium, 1990
AbstractInterstellar polarization and polarization of the sky background is predicted to be significantly smaller in the ultraviolet than in the optical region of the spectrum; while intrinsic polarization is expected to be greater. For these reasons alone ultraviolet polarimetry should provide a powerful diagnostic tool.

Properties, mechanisms, and perspectives of ultrafast laser modifications in silicate glass volume

International Journal of Applied Glass Science, EarlyView.
Abstract Ultrafast laser irradiation of glass enables highly localized structural transformations within the material's bulk, unlocking diverse applications in photonics, data storage, and microfabrication. Here, we provide a concise yet comprehensive overview of the main types of femtosecond laser‐induced modifications in silica‐based glasses (Types I,

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 ...

Application of Deep Learning to Enhance the Computation of Phase Matrices of Nonspherical Atmospheric Particles Across All Size Parameters

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Single‐scattering properties of nonspherical particles are essential to atmospheric radiative transfer and remote sensing studies. In particular, full scattering phase matrices are indispensable for simulating polarized radiative transfer and polarimetry‐based remote sensing.

Polarimetric Wide‐Angle Radar Detects Competing Signatures of Ice Fabric and Structural Firn Anisotropy

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Ice is mechanically and dielectrically anisotropic. The degree of anisotropy evolves dynamically as ice crystals align during deformation into macroscopic patterns termed ice fabric. Radar polarimetry is an emerging tool to detect such patterns, particularly using nadir‐looking antenna geometries sensitive to horizontal anisotropy.
