Bianisotropic Metasurfaces for Optimal Polarization Control: Analysis and Synthesis

Two-dimensional metamaterials (metasurfaces) are desirable for their ability to modify electromagnetic fields--for example, producing perfect absorbers for stealth technologies. Metasurfaces reported to date, however, have demonstrated only limited control over the polarization and phase of these fields. In this work, the authors incorporate metamaterial anisotropy and chirality into calculations to derive simple, general, closed-form expressions relating constituent parameters of an arbitrary bianisotropic metasurface to its reflection and transmission behaviors.
