    "abstract": "We study the effective second-harmonic generation (SHG) susceptibility in\ngraded metallic films by invoking the local field effects exactly, and further\nnumerically demonstrate that the graded metallic films can serve as a novel\noptical material for producing a broad structure in both the linear and SHG\nresponse and an enhancement in the SHG signal.",
