Abstract
Metamaterials proved in the last 15 years to be an extremely flexible and useful concept that has been implemented in many different contexts, from fundamental research to applications . We present a complementary metasurface realised with Niobium thin film which displays a quality factor Q= 54 (see Fig. 1 (a)) at 266 GHz and a fully switchable behaviour as a function of the temperature. The switching behaviour and the high quality factor are due to a careful design of the metasurface aimed at maximising the ohmic ...File in questo prodotto:
