Two-dimensional materials such as graphene have attracted recent interest in many optical and electronical applications. Particularly for nano-optical metasurfaces the use of graphene promises compact tunable devices with broad spectral bandwidth. For example, the high absorption of graphene layers can be used to realize nano-optical polarizers. In this contribution, we investigate the angular dependent polarization properties of graphene as a coating on nano-structured silicon carbide (SiC) samples. To this end, we set up a Mueller matrix polarimeter for wavelengths from 400 to 1650 nm. Further, we developed an effective medium approach to model the experimental results.
