The Design of Dual Band Stacked Metasurfaces Using Integral Equations [PDF]
, 2021 An integral equation-based approach for the design of dual band stacked metasurfaces which are invariant in one-dimension is presented. The stacked metasurface will generate collimated beams at desired angles in each band upon reflection. The conductor-backed stacked metasurface consists of two metasurfaces (a patterned metallic cladding supported by a

Computational Analysis of Metasurfaces [PDF]
IEEE Journal on Multiscale and Multiphysics Computational Techniques, 2018 Metasurfaces represent one of the most vibrant fields of modern science and technology. A metasurface is a complex electromagnetic structure, that is typically deeply subwavelength in thickness, electrically large in transverse size and composed of subwavelength scattering particles with extremely small features; it may generally be bianisotropic ...
