    "abstract": "We show that the finite-difference frequency-domain method is well-suited to\nstudy subwavelength lensing effects in left-handed materials (LHM\u0027s) and\nrelated problems. The method is efficient and works in the frequency domain,\neliminating the need for specifying dispersion models for the permeability and\npermittivity as required by the popular finite-difference time-domain method.\nWe show that \"superlensing\" in a LHM slab with refractive index n = -1 can be\napproached by introducing an arbitrarily small loss term. We also study a thin\nsilver slab, which can exhibit subwavelength imaging in the electrostatic\nlimit.",
