    "abstract": "The time-harmonic electromagnetic responses of (a) a bilayer made of an\nepsilon-negative layer and a mu-negative layer, and (b) a single layer of a\nnegative phase-velocity material are compared. Provided all layers are\nelectrically thin, a restricted equivalence between (a) and (b) exists. The\nrestricted equivalence depends on the linear polarization state and the\ntransverse wavenumber. Implications for perfect lenses and parallel-plate\nwaveguides are considered.",
