Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering

Advanced Optical Materials, EarlyView.
Femtosecond laser surface processing (FLSP) is employed to fabricate titanium‐based metamaterials with engineered micro/nano‐scale features that exhibit spectrally selective and omnidirectional thermal emissivity. By integrating advanced ellipsometry, electromagnetic modeling, and compositional analysis, the work reveals resonance‐driven emissivity ...

Role of spatial coherence in polarization tomography

, 2005
We analyze an experimental setup in which a quasi-monochromatic spatially coherent beam of light is used to probe a paraxial optical scatterer. We discuss the effect of the spatial coherence of the probe beam on the Mueller matrix representing the ...

Complex Structured Light Generation Using Printed Liquid Crystal Droplets

Advanced Optical Materials, EarlyView.
Inkjet‐printed liquid crystal droplets generate structured light beams with spatially varying polarization and phase. These include full Poincaré beam, vortex beam carrying orbital angular momentum, and beam with polarization singularities, offering a simple approach for compact structured light generation in optical manipulation, imaging, and ...

Snapshot Mueller matrix polarimetry by wavelength polarization coding and application to the study of switching dynamics in a ferroelectric liquid crystal cell.

EPJ Web of Conferences, 2010
This paper describes a snapshot Mueller matrix polarimeter by wavelength polarization coding. This device is aimed at encoding polarization states in the spectral domain through use of a broadband source and high-order retarders.

Eigenvalue calibration methods for polarimetry [PDF]

Journal of the European Optical Society-Rapid Publications, 2012
Complex polarisation sensitive systems such as imaging Mueller matrix polarimeters are commonly calibrated using the eigenvalue calibration method. In this paper we present an extensive review of the method and an existing variant.

Interpretation of the mechanism for depolarizing media by using physically realizable and rotatable generators of differential matrix

Results in Physics, 2023
Understanding and revealing the mechanism or the sources of depolarization behaviors of a medium is a crucial problem to be addressed. An interpretation method of expressing depolarizing differential matrix by the physical generators associated with ...

MFP and CFAP Official Announcement and Pre‐Official Announcement Effects on the Corn and Soybean Futures Market

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the official announcement effect of the Market Facilitation Program (MFP) and the Coronavirus Food Assistance Program (CFAP) on the corn and soybean futures market. Using a permutation test and a 2‐stage GLS model, we find no significant official announcement effect.

Parallel decompositions of Mueller matrices and polarimetric subtraction

EPJ Web of Conferences, 2010
From a general formulation of the physically realizable parallel decompositions of the Mueller matrix M of a given depolarizing system, a procedure for determining the set of pure Mueller matrices susceptible to be subtracted from M is presented. This
