title: Analysis of Ag-superlens performances using spatial convolution formulation.
abstract: It is shown that the spatial convolution formulation offers the advantage for direct analysis in the real space of the effects of system-object feature mismatches on the resulting image quality. Imaging systems of various layered Ag-poly(methyl methacrylate) configurations and a variety of square-slit objects were considered for the analysis. The results reveal how those feature mismatches affect the image quality and clarify the previously suggested possible advantage of using a layered Ag superlens over a single-Ag slab of the same total thickness. Those mismatches may eventually be quantified to allow the optimization of a superlens appropriate for imaging a certain object.
