Feasibility of cloaking with isotropic, non-magnetic media, first suggested by Leonhardt in 2006, is a practically important question in theoretical and applied optics. In this paper, Xu et al. show that adding negative magnetic permeability (and negative permittivity) to conformal mapping scenarios leads to accurate eikonal-limit cloaking in the limit of zero loss.
