Abstract (English): After reviewing the requirements, which has to be 
satisfied by a metamaterial based subwavelength imaging system, imaging 
devices made of composite thin films are reported herein. The composite 
is formed by spherical Ag nanoparticles in SiO2 host material. The 
electromagnetic material parameters of the composite material are 
calculated with the classical Maxwell-Garnet mixing rule and Mie theory 
based high frequency effective medium theory. The image of single and 
multilayer metamaterial based imaging systems is investigated, by 
solving the Maxwell equations, with the Transfer Matrix method. The 
formula of the composite material, the optimum working frequency and the 
thicknesses of the layers are determined minimizing the absolute 
difference between the source and image. The details of the design 
procedure are presented and optimized configurations obtained under 
different constrains are discussed.
