Lifetime Testing of Wire-Grid Polarizers with Selected Over-Coatings
<p>Wire-grid polarizers (WGPs) offer superior extinction, durability, angle of incidence, and heat resistance when compared to traditional organic polarizers. WGPs are found in applications such as high lumen lighting, laser devices, high lumen digital cinema projectors, LED packaging, and other …

Design of Submicron Structured Guided-Mode-Resonance Near-Infrared Polarizer
… to reduce cost. For this purpose, a gold (Au) wire-grid transmission-type transverse-magnetic (TM) polarizer and a silicon (Si) wire-grid reflection-type TM polarizer, were designed using the guided-mode-resonance filter. The Au wire-grid TM polarizer of 700nm grating width and 1200nm grating …

Studying phonon mean free paths at the nanoscale : modeling and experiments
… of non-diffusive thermal transport using wire grid linear polarizer in conjunction with time-domain thermoreflectance (TDTR) pump-and-probe measurement setup. Consistent algorithm based on solution from the phonon Boltzmann transport equation (BTE) is also developed to approximately …

INVESTIGATION OF SMALL ANTENNAS FOR PERSONAL HANDY PHONE USE
… patterns agree well confirming the valid of wire-grid model. This antenna can realize the functions of receiving and transmitting at the same time. Because of the limitation of MTLA for application at higher frequency, we have designed a new type of antenna array for PHP use. A 2-way hybrid …

Studies of non-diffusive heat conduction through spatially periodic and time-harmonic thermal excitations
… approach based on microfabricating 1D wire grid polarizers on the surface of a material under study. This work finds that the dominant thermal length scales in polycrystalline Bi 2Te3 are smaller than 100 nm. We also determine that even small amounts of direct sample optical excitation, …
