Analytical analysis for impact of polarization aberration of projection lens on lithographic imaging quality

, 2015
In high-NA and hyper-NA lithography systems, the polarization aberration of projection lens leads to imaging degradations. Typically, numerical simulations are used to explore the relationship.

Reducing symmetric polarization aberrations in a lens by annealing

Optics Express, 2004
Radially symmetric retardance was found in antireflection coated, molded aspheric glass lenses by measurement with a Mueller matrix imaging polarimeter. The source of the unexpected polarization aberration is traced to a remarkably symmetric radial stress birefringence in the glass believed to arise during fire-polishing of the surfaces.

Aberration-corrected transmission electron microscopy with Zernike phase plates

, 2022
We explore the possibility of applying physical phase plates (PPs) in combination with aberration-corrected transmission electron microscopy. Phase-contrast transfer characteristics are calculated and compared for a thin-film based Zernike PP, a hole ...

Quantification and characterization of ultrasound-induced polarization wavefront aberration in the phase space [PDF]

Light propagation wavefront and photon composition variations occur when the beam encounters acoustic waves, bringing mechanical and chemical inhomogeneity-induced light-intensity modulation, while phase variations, which carry more information about the

Cathodic polarization-induced structural evolution of oxide film on the 654SMO super austenitic stainless steel

Corrosion Communications
Cathodic polarization is often used as a pretreatment procedure before electrochemical measurement of a certain passive metal material, aiming to remove the natural oxide film and obtain a fresh metal surface.

Mapping grain boundary heterogeneity at the nanoscale in a positive temperature coefficient of resistivity ceramic

APL Materials, 2017
Despite being of wide commercial use in devices, the orders of magnitude increase in resistance that can be seen in some semiconducting BaTiO3-based ceramics, on heating through the Curie temperature (TC), is far from well understood.
