DALARSSON, R. MITTRA a reasonable resemblance of actual design structures like the one described in Table 1 and Fig. Key words: Flat lenses, Graded permittivity and permeability models, Transformation Optics, Exact analytical solutions 1. INTRODUCTION Flat lenses designs based on Transformation Optics (TO) and using left-handed (negative refractive index) metamaterials have been discussed in a number of recent publications ([1], [2]).	cache/fuelectenerg-2758.pdf	txt/fuelectenerg-2758.txt
