Abstract:Our study introduces a metamaterial (MM) with a straightforward disk-like configuration that exhibits two prominent absorption peaks at wavelengths of 3960 and 4197 nm, with absorption of 96.3% and 94.1%, respectively. The design not only proved to be convenient for the practical fabrication, but also revealed a resilience to the changes in structural parameters. Moreover, this offers versatility across a wide range of applications, due to the polarization-independent behavior. Additionally, the investigation … Show more
