摘要：

Refractory titanium nitride (TiN) nanoellipsoid was proposed as unit component for metamaterial perfect absorber in visible frequencies. Combining both the intrinsic loss of the TiN material in short wavelength (<500 nm) and the plasmonic resonance absorption in long wavelength (>500 nm), the metamaterial perfect absorber based TiN nanoellipsoid array can be a broadband perfect absorber in whole visible region. An average absorbance of 98.5 % over the whole visible spectrum was obtained with a total thickness of only 200 nm. The structure is directly applicable to all kinds of opaque substrates with no need for metallic bottom.
