We present theoretical and experimental proofs that our synthesized composite material with silver nanoparticles has a quasi-zero refractive index over a wide wavelength range, and the enhanced optical transmission is observed in the material layer. The formulas of the reflectance and transmittance of a layer with a quasi-zero refractive index are consistent with the experimental data. The optical...
Dielectric behavior (complex permittivity and loss) of iron-containing (5–20 wt.%) polymeric composite nanomaterials are investigated in the range from 2 to 18 GHz.
Prospects of creation of new type of non-volatile memory based on composite with stabilized nanoparticles are offered. The given type of memory can have a big stock on increase in density of recording of the information. The second essential advantage of the given type of memory will be rather simple process of repetition work. These two key factors are very important for the market of compact non-volatile...
Investigations of the dielectric properties hysteresis formation in the artificial composite media based on the nanoparticles of the oxides and sulfides of the transition metals (copper, zinc, cobalt, cadmium) stabilized into the low density polyethylene (LDPE) matrix were carried out. Also investigation of the transition processes with the different metals contact were carried out. Mechanism of the...
In work the results of an experimental research of optical spectra of nanocomposites based on superdispersed particles of iron, its compounds, and also high pressure polythene matrix are given. Samples were synthesized by the method described in and represented plates by thickness 0,4-0,5 mm made by a method of mechanical hot pressing. The transmission and reflection spectrums of samples were measured...
