A near infrared MIM metamaterial absorber using SiC

Abstract

In this study, we introduce a metamaterial absorber operating in the near infrared region. The current metamaterial absorber (MMA) comprising Silver-SiC-Gold demonstrates an absorptivity exceeding 80% within the wavelength range of 770 nm to 1150 nm. The current metamaterials absorber exhibits independence from both polarization and incident angle. Additionally, we made comparison between the proposed Metal-Insulator-Metal (MIM) based MMA with other previously reported MMA using Silicon Carbide (SiC) and another dielectric spacer layer.
