Extended Representation of Mueller Matrices

open access: yesPhotonics, 2023
The so-called arbitrary decomposition of a given Mueller matrix into a convex sum of nondepolarizing constituents provides a general framework for parallel decompositions of polarimetric interactions.

A Unified Vector Electromagnetic Framework for Ionospheric Scintillation and Polarization Effects in GNSS

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...

Ubiquitous Antiparallel Domains in 2D Hexagonal Boron Nitride Uncovered by Interferometric Nonlinear Optical Imaging

open access: yesAdvanced Materials, Volume 38, Issue 25, 4 May 2026.
Interferometric second‐harmonic generation (SHG) imaging reveals the ubiquitous formation of antiparallel domains in CVD‐grown 2D hexagonal boron nitride. By resolving lattice orientation and SHG phase, hidden domain structures and disorder become visible over large areas. The SHG intensity quantitatively tracks crystalline quality across growth routes,

Proposed Methods For Measuring and Interpreting Mueller Matrices in In Vivo Retinal Polarimetry [PDF]

open access: yes, 2020
Mueller matrix polarimetry is the examination of how a sample transforms the polarization state of light. This requires probing the sample with input light of a variety of generated polarization states and analyzing the resulting output states, using a ...

Synthesis, Structure, and Thin Film Optical Properties of a Chiral Benzothiazole‐Derived Squaraine

open access: yesChemPhysChem, Volume 27, Issue 7, 14 April 2026.
Solution‐processed thin films can be sensitive to the choice of solvent and thermal annealing, which we explore for a chiral benzothiazole squaraine. We observe peculiarly shaped excitonic circular dichroism in uniaxially anisotropic thin films, in which the presumed Davydov bands are spatially distributed exclusively into in‐plane (UDC) and out‐of ...

Demonstration of Compact In situ Mueller-Matrix Polarimetry Based on Binary Polarization Rotators

open access: yesIEEE Access, 2019
We develop a compact in situ Mueller-matrix polarimetry (MMP) based on binary polarization rotators for on-machine optical processing measurements. The presented in situ MMP could measure the polarization properties of free-space reflective samples by ...
