Abstract

We demonstrate that subwavelength surface textures can enhance the thermal emissivity of a structure. In this study, four different texture patterns are used, including 2D rectangular and triangular strips, 3D square and triangle chips, with different materials used as substrate. Texture material is selected as titanium dioxide due to its high refractive index. The effect of the geometry on the emissivity is parametrically studied, and global optimization is used to maximized infrared emissivity by altering the of 2D rectangular and triangular strips. The results show that a rigorous design procedure can yield a significant improvement in the emissivity of structures.
