Abstract

We proposed an effective metamaterial infrared (IR) emitter by using MEMS microheater with different pattern density. A highest heating efficiency of MEMS microheater is under the pattern density of 49%. The metamaterial is composed of π ·shape nanostructures on the surface of MEMS microheater to form a metamaterial IR emitter. By changing gap width of π shape metamaterial, the emissivity of IR emitter is blue shift and enhances its emissivity. The emissivity of metamaterial IR emitter is 0.94 at wavelength of 5μm. Such design is able to exhibit a narrowband wavelength in IR wavelength range.
