Exploiting Two‐Photon Lithography, Deposition, and Processing to Realize Complex 3D Magnetic Nanostructures

Advanced Functional Materials, EarlyView.
Two‐photon lithography (TPL) enables 3D magnetic nanostructures with unmatched freedom in geometry and material choice. Advances in voxel control, deposition, and functionalization open pathways to artificial spin ices, racetracks, microrobots, and a number of additional technological applications.

Mueller's Exchange-Correlation Energy in Density-Matrix-Functional Theory [PDF]

, 2009
The increasing interest in the Mueller density-matrix-functional theory has led us to a systematic mathematical investigation of its properties. This functional is similar to the Hartree-Fock functional, but with a modified exchange term in which the ...

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Using a dynamic Mueller matrix in modeling of retinal birefringence scanning systems

Results in Optics, 2023
Polarization modeling by means of the Mueller matrix formalism is widely used for representation and optimization of the performance of complex polarization-sensitive systems. Yet, this turns out to be a challenge, as soon as such systems become dynamic,

Autofluorescent polarimetry in diagnostics of endometriosis and infertility [PDF]

, 2015
A new information about optical technique in diagnostics for the endometrium structure has been proposed. The model of Mueller-matrix description of mechanisms responsible for optical anisotropy of these objects (optical activity, birefringence as well ...

Resistance of Oil‐Infused PDMS with Different Macroporosities Against Bacterial Attachment

Advanced Materials Interfaces, EarlyView.
In this study, a series of environmentally benign, nonfluorinated liquid paraffin‐infused porous PDMS networks with varying porosities is created. By introducing different homogenous and heterogenous bulk structures and varying interfacial roughness by sugar and salt templating, the role of porosity and oil availability on the resistance against ...

Correlation of Optical Constants and Morphologies with Mueller Matrix for Micro-Rough Surfaces

Applied Sciences
This paper focuses on the coupling relationships between the optical constants (n: refractive index; k: extinction coefficient) and Mueller matrix elements, as well as between the morphological parameters (σ: root mean square roughness; τ: correlation ...

Full-Field Stokes–Mueller Matrix Imaging Polarimetry System Based on Electro-Optical Modulators

IEEE Photonics Journal, 2018
A new full-field Stokes–Mueller polarimetry system with no moving parts is proposed for imaging the Mueller matrix of optical samples. The polarization state generator (PSG) of the proposed system contains two electro-optical (EO) modulators to ...

Deriving Telescope Mueller Matrices Using Daytime Sky Polarization Observations

, 2011
Telescopes often modify the input polarization of a source so that the measured circular or linear output state of the optical signal can be signficantly different from the input.

Modeling the optical properties of self-organized arrays of liquid crystal defects [PDF]

, 2014
International audienceLocal full Mueller matrix measurements in the Fourier plane of a microscope lens were used to determine the internal anisotropic ordering in periodic linear arrays of smectic liquid crystal defects, known as 'oily streaks'.
