Transformation electromagnetics devices using tensor impedance surfaces
A method for designing transformation electromagnetics devices using tensor impedance surfaces (TISs) is presented. The method allows anisotropic TISs to be designed that can support tangential wave vector distributions and power flow directions specified by a coordinate transformation. A beam-shifting device is designed using an anisotropic surface that allows a surface wave with a Gaussian profile to be shifted laterally at 10 GHz. The design is verified with a commercial full-wave solver. This work opens new opportunities for the design and implementation of surfaces that can guide or radiate electromagnetic fields.
