The optical properties of discontinuous copper films on quartz substrates at volume fractions ranging from 0.19 to 1.0 are investigated. The range of dielectric properties, the percolation threshold, and the range of metallic properties are determined. The transmittance spectra of copper films with low volume fractions are interpreted in terms of a modified(More)
Pt films with mass thicknesses ranging from 0.6 to 3.9 nm were evaporated onto quartz-glass substrates under vacuum conditions (p ~ 10(-4) Pa) with evaporation rate 0.01 to 0.2 mm/s. The transmittance spectra were measured in the wavelength range from 220 to 2500 nm. The microstructures were examined by a transmission electron microscope. The statistical(More)
Selected properties of photovoltaic (PV) structures based on n-type zinc oxide nanorods grown by a low temperature hydrothermal method on p-type silicon substrates (100) are investigated. PV structures were covered with thin films of Al doped ZnO grown by atomic layer deposition acting as transparent electrodes. The investigated PV structures differ in(More)
In this study, optical properties of gold and aluminum island films are described in terms of a classical macroscopic model. The distributions of island diameters and interisland spacing are assumed to be lognormal. The study also involves the effective permittivity of the surrounding. There is good agreement between theoretical and experimental results,(More)
This paper presents an approach to construct efficient and extensible multi-agent platform for distributed soft computing. Various software engineering techniques are employed to implement reliable and reusable system architecture. Extensible XML based configuration is used to simplify the process of repetitive simulations performed with use of constructed(More)
