In this paper, Transformation Optics is exploited to design anisotropic modulated metasurfaces able to control the wavefront and Poynting vector distribution of surface waves. This methodology can be applied to design a large number of planar devices. As an example, a beam shifting device has been implemented using a metasurface consisting of dipoles printed on a grounded slab. The capability of the device to laterally shift a surface wave has been verified through full wave simulations.

Abstract
In this paper, Transformation Optics is exploited to design anisotropic modulated metasurfaces able to control the wavefront and Poynting vector distribution of surface waves. This methodology can be applied to design a large number of planar devices. As an example, a beam shifting device has been implemented using a metasurface consisting of dipoles printed on a grounded slab. The capability of the device to laterally shift a surface wave has been verified through full wave simulations.
