Synthesis of Spherical Metasurfaces based on Susceptibility Tensor GSTCs (1710.00040v2)
Published 7 Sep 2017 in physics.app-ph, physics.class-ph, and physics.med-ph
Abstract: The bianisotropic susceptibility Generalized Sheet Transition Conditions (GSTCs) synthesis method is extended from planar to spherical metasurfaces. Properties specific to the non-zero intrinsic curvature of the spherical shape are highlighted and different types of corresponding transformations are described. Finally, the susceptibility-GSTC method and exotic properties of spherical metasurfaces are validated and illustrated with three examples: illusion transformation, ring focusing and birefringence.
