Spectral emittance and thermal stability of two-dimensional W gratings were investigated to obtain high-temperature resistive selective emitters. Numerical calculations based on rigorous coupled-wave analysis were performed to determine the structural profile of gratings with good spectral selectivity. The results indicate that the grating with 200 nm wall thickness shows very high thermal stability over 1400 K, while the polycrystalline grating is deformed at a high temperature because of the grain growth.
