Demo 24-06 Polarization by Double Reflection
, 2001 Polarization of light is obtained by using two reflections from dielectric plates, as in Figure 1. This demonstration illustrates the effect of double reflection on the polarization of an initially unpolarized light beam.

Advanced Functional Materials, EarlyView.P4bm framework in NaNbO3‐Ba(Ti, Hf)O3 ferrodistortive relaxor entails short‐range and highly‐polar ferrodistortive orders. The abundant highly‐polar orders facilitate to increase entropy change, and robust octahedral oxygen tilt enables to impede thermal perturbations.

Diffraction Focal Position and Vector Diffraction Theory for Micro Holographic Storage Systems
Applied Sciences, 2014 In this study, we proposed a method to determine the optimal focal position for micro-holographic storage systems, using vector diffraction theory; the theory provides exact solutions when the numerical aperture (NA) exceeds 0.6.

Demo 24-05 Polarization by Reflection
, 2001 Light waves can be polarized by reflection from a dielectric surface, as shown in Figure 1. The amount of polarization depends on the angle at which the light strikes the surface, with the maximum effect occurring at an angle called the Brewster angle,

Signatures of Black Hole Spin and Plasma Acceleration in Jet Polarimetry. II. Off-axis Jets
The Astrophysical JournalWe analyze the polarization of optically thin, stationary, axisymmetric black hole jets at scales of order the light cylinder radius. Our work generalizes the face-on results of Z. Gelles et al. to arbitrary viewing inclination.

Primary aberrations in focused radially polarized vortex beams
Optics Express, 2004 We study the effect of primary aberrations on the 3-D polarization of the electric field in a focused lowest order radially polarized beam. A full vector diffraction treatment of the focused beams is used. Attention is given to the effects of primary spherical, astigmatic, and comatic aberrations on the local polarization, Strehl ratio, and aberration ...

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film
Advanced Functional Materials, EarlyView.ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...
