Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.Abstract In this study, an Accelerated Discrete Ordinate Method (ADOM) is proposed to enhance the computational efficiency of multi‐layer radiative transfer (RT) simulations while maintaining a high accuracy. ADOM applies the Discrete Ordinate Method (DOM) only in scattering layers, while the radiances for the adjacent clear‐sky layers are merged and ...

Polarimetric SAR urban classification using the Touzi target scattering decomposition
Canadian Journal of Remote Sensing, 2011 The Touzi decomposition was recently introduced for a roll and unique incoherent decomposition of target scattering. Unlike the Cloude–Pottier incoherent target scattering decomposition, no scattering parameter averaging is performed and target scattering is fully characterized by an in-depth analysis of five parameters for each of the three (dominant,

Polarization‐sensitive diffractive optics and metasurfaces: “Past is Prologue”
Nanophotonics, Volume 14, Issue 23, Page 3825-3834, 02 November 2025.Abstract Polarization control and switchability are among the most unique features of “metasurfaces” as compared with diffractive optics technologies of the past. Here, we review how the polarization control afforded by the advent of present‐day metasurfaces compares to diffractive elements of previous decades, clarifying from a functional perspective ...

IEEE Access, 2018 Numerous radar polarimetry theories and polarimetric synthetic aperture radar (PolSAR) processing methods have been developed. However, the vast majority of SAR images are not fully polarimetric (full-pol).

Application of metasurface in future displays
Nanophotonics, Volume 14, Issue 22, Page 3527-3555, 01 November 2025.Abstract Optical metasurfaces, as a booming research field, have provided new methods for modulating the amplitude, phase, and polarization of light through artificial birefringent structures or structural resonances. It has been used to design planar optical components such as ultra‐thin lenses, ultra‐wideband achromatic lenses, and orbital angular ...

Detecting covariance symmetries for classification of polarimetric SAR images [PDF]
, 2016 The availability of multiple images of the same scene acquired with the same radar but with different polarizations, both in transmission and reception, has the potential to enhance the classification, detection and/or recognition capabilities of a ...
