We theoretically propose a simple ultra-narrow multi-band perfect absorber for sensing
applications. The perfect absorber consists of periodically arranged metallic nanodisks …

We theoretically present a tunable dual-band perfect absorber in the visible and near-
infrared regions for sensing applications. The absorber consists of a periodic metal-dielectric …

The size-controllable and ordered Al nanocavities and nanodomes arrays were synthesized
by electrochemical anodization of aluminum using phosphoric acid, citric acid and mixture …

It is desirable to have electromagnetic wave absorbers with ultrathin structural thickness and
broader spectral absorption bandwidth with numerous applications in optoelectronics. In this …

Integrating plasmonic nanostructures with functional materials can further control over the
optical resonant responses. A perfect absorber (PA) consisting of aluminum (Al) ring array …
