Concept of variable or non-uniform metasurfaces allows a very high level of control over the electromagnetic wave paths. In this paper this control is achieved by gradually modifying the geometry of subresonant printed patches on a grounded dielectric substrate. This allows us to change the phase velocity or the propagation path of the guided wave. This property was used to design a Luneburg lens which was then inserted into an H-plane horn to improve the horn's radiation characteristics. The results of this idea are demonstrated using full wave simulations, showing the applicability of this concept.
