The optical properties of composite material made of metal nanospheres situated in the sites of three-dimensional lattice and embedded into dielectric matrix are considered. It is demonstrated that index of refraction of composite medium may acquire unit value at certain relations between dielectric constants. The method is developed for the description of optical properties of composite medium that takes into account retardation effects in nanospheres interactions. It is shown that obtained results coincide with Maxwell-Garnett theory in the limit of infinitesimal distances between nanospheres with respect to wavelength.
