In this paper, a metasurface-based ultraviolet absorber made of periodically arranged nanospheres of indium tin oxide (ITO) is studied. The wideband absorptivity was observed due to photonics resonance of the top metasurface with an aggregative absorption of over 85% within the 200–320 nm operating range. The proposed absorber features insensitivity to different polarized waves. Furthermore, we employ the Fabry-Pérot model to understand the absorption mechanism and these results show a fair agreement with our simulated work. This absorber can be useful to use in applications related to photodetection conversion and ultraviolet protection.
