The acquisition speed of terahertz time-domain spectroscopy systems has undergone a significant improvement in recent years. With the development dual-laser-based sampling techniques such as ASOPS or ECOPS, waveform rates kilohertz range have become feasible. Here, we present measurements sub-wavelength layers multilayer at rate 1.6 kHz, where individual layer thicknesses are analyzed real time...

Yttrium-stabilized zirconia thermal barrier coatings (TBCs) of combustion chambers and piston crowns are used most frequently to increase the chamber temperature internal engine efficiency. The development multilayer metal matrix composite coating is great importance diminish ceramic coating’s brittleness susceptibility degradation providing similar insulation. Our group developing TBCs based o...

The internal stresses of plasma-sprayed multilayer ytterbium disilicate environmental barrier coatings were measured using microfocused high-energy X-rays in a transmission geometry. Stresses were measured for as-sprayed and ex-situ heat-treated ytterbium disilicate topcoats at room temperature and during in-situ heating and cooling experiments. In-situ loading experiments were also performed o...

In order to analyze the influence of methods to design antireflection coatings (ARCs) on reflectivity of broadband solar cells, we provide detailed analyses about the ARC coupled with a window layer and the refractive index dispersion effect of each layer. By multidimensional matrix data simulation, two methods were employed to measure the composite reflection of a SiO2/ZnS double-layer ARC wit...

Closed field” magnetron (CFM) sputtering offers a flexible and high throughput deposition process for optical coatings and thin films required in display technologies. CFM sputtering uses two or more different metal targets to deposit multilayers comprising a wide range of dielectrics, metals and conductive oxides. Moreover, CFM provides a room temperature deposition process with high ion curre...

In this review, some important designs of stimuli responsive and chemically reactive multilayer coatings were presented to display the inherent ability such interfaces in associating different relevant, functional bio-inspired properties.

The limit sensitivity of interferometric gravitational wave antennas is set by the thermal noise in the dielectric mirror coatings. These are currently made of alternating quarter-wavelength high/low index material layers with low mechanical losses. The quarter-wavelength design yields the maximum reflectivity for a fixed number of layers, but not the lowest noise for a prescribed reflectivity....
