As part of our research on materials for concentrator photovoltaics (CPV), we are evaluating
the optical properties and solar radiation durability of a number of polymeric materials with …

Alumina toughened zirconia (ATZ) and zirconia toughened alumina (ZTA) are currently the
materials of choice to meet the need for tough, strong, and bioinert ceramics for medical …

We present the design, fabrication and characterization of high-Q (Q= 36,000) polymeric
photonic crystal nanobeam cavities made of two polymers that have an ultra-low index …

Development of a 2D metamaterial that preferentially emits broadband circularly-polarized
(CP) infrared radiation is hindered by the fact that orthogonal electric-field components are …

The transmittance values measured in IR reflection-absorption (RA) spectra were used to
determine the optical constants of dielectric films laid on solid substrates. In order to obtain …

The present study investigates the main electrical transport mechanism in V 2 O 5 thin films
deposited by RF magnetron sputtering on the basis of the Mott's small polaron hopping …

Reflectarray designs at infrared (IR) frequencies are investigated in this paper. At the short-
wavelength region, material loss becomes an important consideration in reflectarray …

A synthesis method has been developed for preparation of vanadium oxide thermometer
thin film for microbolometer application. The structure presented is a 95-nm thin film …

Frequency Selective Surfaces (FSS) are periodic array of sub-wavelength antenna
elements. They allow the absorptance and reflectance of a surface to be engineered with …

We present a novel reflective quarter-wave plate comprised of subwavelength meanderline
elements. The device is operational over the long-wave infrared (LWIR) spectrum, with …
