An open chiro-waveguide enabled by anisotropic impedance surfaces

Metasurfaces, which are quasi-two-dimensional (quasi-2D) textured surfaces comprised of a periodic or aperiodic array of sub-wavelength building blocks, provide a fully-planarized platform for controlling the propagation, radiation, and scattering of electromagnetic waves. Compared to their three-dimensional (3D) metamaterial counterparts, 2D metasurfaces… (More)
