title = "Broadband circular polarizer formed by stacked plasmonic metasurfaces",
abstract = "Recent ideas involving plasmonic metamaterials have been put forward to enhance the overall bandwidth of operation of quarter-wave plates for circular polarization detection. The proposed metamaterial geometries are inherently complex to realize and difficult to scale beyond the near-infrared frequencies. Here, we show how proper stacks of lithographically printed plasmonic metasurfaces with simple patterns may provide large extinction ratios for the detection of circular polarization, combined with broadband operation and simplicity of design and realization. In this paper, we will discuss some physical insights into the modeling of these structures, fundamental advantages and some limitations of this approach.",
