Abstract

Using the multiple-scales homogenization method, we derive generalized sheet transition conditions (GSTCs) for electromagnetic fields at the surface of a metascreen. A metascreen is a metasurfaces with a ``fishnet'' structure. These surfaces are characterized by periodically spaced apertures in an otherwise relatively impenetrable surface. The apertures that compose the metascreen are of arbitrary shape and are embedded between two different magneto-dielectric media. The parameters in these GSCTs are interpreted as effective surface susceptibilities and surface porosities, which themselves are related to the geometry of the aperture that constitute the metascreen.
