 note = {Thermal stability as well as optical properties of submicron-period microstructures on W surfaces has been investigated for developing new radiation control devices in space. Numerical calculations based on rigorous coupled-wave analysis are performed to determine the structural profile of gratings with good spectral selectivity. According to the determined parameters, two-dimensional W gratings composed of rectangular microcavities with the period of 1.0 micrometer are fabricated on single crystalline and polycrystalline W substrates. The grating shows a strong emission peak, which can be explained by the confined modes inside the cavities. The grating with 200 nm wall thickness made from a single crystalline W shows very high thermal stability over 1,400 K, while the polycrystalline grating is deformed at a high temperature because of the grain growth. It is confirmed that the thermal stability has been improved by using single crystalline substrates., 資料番号: AA0045438044},
