The polarization properties of a tilted polarizer
Optics Express, 2013 Polarizers are key components in optical science and technology. Thus, understanding the action of a polarizer beyond oversimplifying approximations is crucial. In this work, we study the interaction of a polarizing interface with an obliquely incident wave experimentally.

Broadband spectral shaping using nematic liquid crystal
Results in Physics, 2019 We demonstrate what is, to our knowledge, the first implementation of nematic liquid crystal (LC) for spectral shaping of broadband light fields. A LC cell of several microns thickness is placed between a polarizer and an analyzer.

Broadband and tunable terahertz absorption based on ethanol-treated carbon nanotube sponges
Results in Physics, 2022 To eliminate the undesired terahertz (THz) interference and echo, broadband and tunable THz absorbing devices are urgently needed. Herein, we report a simple method to obtain an active THz absorption performance by ethanol-treated carbon nanotube sponges

Mueller Matrix Imaging Optimized by Uniform Illumination
Frontiers in Physics, 2022 In this study, we present a flat-field Mueller matrix imaging system to reduce the reconstruction error caused by critical illumination. This study demonstrates that the signal-to-noise ratio (SNR) of the reconstructed images is improved by about eight ...

Journal of Algebra, 2003 The purpose of this paper is to study finite-dimensional Lie algebras over a field k of characteristic zero which admit a commutative polarization (CP). Among the many results and examples, it is shown that, if k is algebraically closed, the nilradical N of a parabolic subalgebra in A_n and C_n has such a CP.

Design of Hollow Core Bragg Fibers for a Compact Fluorescence Sensing Scheme
IEEE Photonics Journal, 2017 We propose a compact fluorescence sensing scheme based on hollow core Bragg fibers (HCBFs) that simultaneously serve as a sample cell, a collector, and a delivery channel for the desired fluorescence, as well as a filter for the residual excitation light

SIAM Journal on Optimization, 2019 The Moreau envelope is one of the key convexity-preserving functional operations in convex analysis, and it is central to the development and analysis of many approaches for convex optimization. This paper develops the theory for an analogous convolution operation, called the polar envelope, specialized to gauge functions.
