The purpose of this study is to clarify the optical characteristics of a Tungsten SiO2-based film-couple metamaterial with a fishnet-shaped grating, and we aim to show that this structure could potentially be used a solar selective absorber for a solar thermophotovoltaic system. The proposed film-coupled metamateris absorber combined with a fishnet-shaped grating shows significant enhancement in its absorption in the spectral region compared with a flat Tungsten surface, and it keeps its spectral emission low in the infrare region, thereby reducing radiative heat loss. The underlying mechanisms of the proposed absorber are discusse through a 3D full-wave electromagnetic simulation, the results of which are compared with that of theoretic equations. Furthermore, its spectral absorption under oblique incident light at the transverse magnetic am transverse electric waves is scrutinized. The underlying absorption mechanisms and relations between eac optical resonance are discussed in this paper and will prove to be fundamental not only in the design of selective absorbers but also in other wavelength-selective thermal radiation controlling devices.
