The Veselago Lens as a Scattering Problem: 2D Solutions Through Asymptotics

This contribution focuses on the analytical derivation of the Green's function of the ideal lossless Veselago lens. The problem is dealt with by considering the lens as a scattering object. Then, the electromagnetic field of a line-source illuminating the lens is seen as the sum of the field due to the line-source in free space plus the scattered field due to the lens. The asymptotic evaluation is exploited to evaluate the thus obtained field integral representation. The approach is also a step towards the truncated lens case.
