© 2019 IEEE.The conventional Veselago-Pendry (VP) lens with ϵ = μ =-1 can be derived via real-valued transformation optics (TO) technique. We extend such approach to complex coordinates to study generalized Veselago-Pendry (GVP) lenses. The derived material properties are doubly anisotropic and impedance matched to free space for all angles of incident. In addition, because the loss is incorporated into the coordinate transformation through an imaginary part of the coordinate transformation, its performance is, in a certain sense, immune to losses. We study different transformation profiles for the imaginary part of the coordinate transformation, i.e, non-symmetric, mirror-symmetric ({mathcal{P}}{\mathcal{T}} symmetry), resulting in a loss, gain, and balanced loss/gain media.
