Metasurfaces represent the most promising class of metamaterials for real applications, whereby arbitrary wavefront and polarisation control can be achieved using just a single sub-wavelength layer. Therefore, allowing tunability over their capabilities is the next step to consolidate them as devices for light control.

In recent years, several approaches to attain tunability have been proposed but most of them involve complex manufacturing processes. Moreover, the influence of the tunable system is not negligible, reducing metasurface efficiency.

During my thesis, I explored reconfigurable flexible systems for multifunctional metadevices. In this talk I review my efforts to produce a novel platform for creating tunable microwave devices based on structural tuning. My study shows that the integration of a patterned elastic substrate (silicone)
