Abstract
A metasurface that is designed to control electromagnetic radiation (EMR) in ways that perform more than a single function. The metasurface has a substrate layer that has multiple asymmetric nanofeatures, each having a height (H) between λmin/100 and 2λmax. Each nanofeature has a particular length (Dy) that extends along a principal in-plane direction θ and a width (Dx) that is orthogonal thereto. Each nanofeature is tailored to scatter with different patterns one polarization state of electromagnetic radiation and one orthogonal polarization state of electromagnetic radiation.
