Quality of Focusing Electromagnetic Radiation by a Plane-Parallel Slab with a Negative Index of Refraction

摘要

The quality of focusing a field by a plane-parallel slab made of a material with permittivity and permeability ε = μ - 1 is analyzed. Fields produced by one or two current filaments that are located near the slab are considered. Causes limiting the available resolution of the system are determined.
