Abstract
Three-dimensional metamaterial absorbers were applied for ultra-sensitive infrared spectroscopic molecular detection devices. Various types of 3D MIM metamaterial absorbers have been proposed for solid, liquid, and gas samples. Owing to their strong resonant absorption, unwanted background in IR spectroscopy was suppressed, and the signal-to-background ratios has been improved. For gas detection, a 3D co-axial double-cylinder structure is introduced as the unit structure of the metasurface absorber.
