The Wave Flow Effect on a Plane Boundary between Vacuum and an Optical Medium with a Quasi-Zero Refractive Index
Results of theoretical and experimental researhes of new metamaterial with silver nanoparticles in a dielectric matrix are presented. This metamaterial is synthesized on the technology developed by us, samples of coatings on glass, silicon and a surface of serially let out silicon solar elements by means of technology of pneumatic dispersion of nanosuspension are received. On the basis of experimental spectra of reflection and a transmission of layers from the metamaterial synthesized by us effects of an interference of light in thick layers, the enhanced optical transmission, a broadband optical antireflection of surfaces are found. The received metamaterial possesses small absorption and small refractive index. It is proved that the refractive index of metamaterial is a random variable and area of admissible values of refractive index of this metamaterial, smaller units, is determined by an arrangement of interferential minima in experimental spectra of reflection of a layer. Formulas for reflective and refractive abilities of a layer with quasi-zero refractive index which correctly describe experimental spectra of reflection and a transmission of a layer are removed. On the basis of the developed theory of optical properties of a composite layer with quasi-zero refractive index new effects such as localization of photons on layer border, focusing of light in a layer, a wave flow effect are predicted by light of a surface of a layer. It is shown that new material with quasi-zero refractive index can find broad application in science and equipment, for example, in optical instrument making, solar industry, quantum electronics.
