Abstract
This work presents a theory of metasurface transformation which extends Transformation Optics 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 approach, combined with the use of tunable metasurfaces, may lead to the realization of a large number of unconventional adaptive devices. © 2013 EurAAP.
