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.
