Abstract
This work presents an extension of Transformation Optics (TO) to control the wavefront of surface waves (SW) through the use of modulated metasurfaces. As the outputs of the conventional TO approach are the metamaterial constitutive parameters able to perform a certain modification of the ray-field path, here the outcomes are the components of the metasurface reactance tensor. This methodology can be applied to design a large number of planar devices including lenses, beam splitters and invisibility cloaks. © 2013 IEEE.
