The material parameters of nano-fishnet optical metamaterials are evaluated numerically through
extraction from reflection and transmission coefficients of structures consisting of multiple nano-fishnet
pairs. For extraction the Nicholson-Ross-Weir method was modified. Effects of
convergence with increase of number layers are discussed. Bulk electrodynamics parameters of
the structure are discussed.
It is known, that along linear chains from silver nano-particles, located in a dielectric matrix, the waveguide modes can propagate in a range of visible light. Such structures recently were investigated with reference to creation of some types of optical subwavelength wave guides. In the present paper the analytical model of a waveguide formed by a one-dimensional array of parallel silver cylinders (this mode has been recently found on the basis of numerical modelling) is suggested. In our work the possibility to use two parallel arrays of cylinders for formation the near-field images of linear light sources in a far zone is considered (an analogue of the ideal lens of J.B. Pendry).
