Experimental Study of a Quad-Band Metamaterial-Based Plasmonic Perfect Absorber as a Biosensor
We present a metamaterial-based perfect absorber (PA) that strongly supports four resonances covering a wide spectral range from 1.8 µm to 10 µm of the electromagnetic spectrum. The designed perfect absorber has metal–dielectric–metal layers where a MgF<sub>2</sub> spacer is sandwiched b...
