The scope of the doctoral thesis is the analytical investigation of planar and wedge-shaped double-negative metamaterial structures. Regarding the planar slab, an integrated method for the investigation of its focusing characteristics is introduced. More specifically, the transfer coefficient from the source to the focus plane is used for the determination of the system's resolution. Furthermore, two new correlation criteria, based on the concepts of correlation coefficient and mean-square error, are proposed for the extraction of the optimum focus plane position. The efficiency of the method is, extensively, tested by means of a theoretical and a numerical analysis. Successively, the field dynamic behavior of the planar geometry is examine...
