Özet
In this study a tunable metasurface has been presented and evaluated for different excitation types. Tunability has been achieved by changing the substrate and geometrical properties. In order to obtain uniqueness, a parameter retrieval for the effective permittivity and permeability is performed using a version of the Nicholson-Ross-Weir (NRW) algorithm that is improved by implementing the Kramers-Kronig relationship. The results regarding the parametric and retrieval analysis are presented.
