Abstract :
Although intensive research efforts have been performed to realize compact/portable metamaterial absorbers, the super absorbing metasurface for ultraviolet (UV) wavelengths has not been reported. Here, we propose an aluminum-based metal-dielectric-metal patterned structure to realize super absorption and strong field localization for UV wavelengths. Its feasibility to function as a high performance substrate for UV surface-enhanced Raman spectroscopy will also be discussed.
