An ultra-broadband and multi-frequency switchable terahertz absorber based on a patterned VO 2 multilayer stacked architecture
Abstract
enables the absorber to exhibit pronounced multi-frequency absorption properties, where six strong absorption peaks with absorption rates over 90% are observed, corresponding to the absorption frequency points of 3.26 THz, 6.68 THz, 7.69 THz, 9.26 THz, 10.32 THz and 13.09 THz, respectively. Furthermore, by employing a symmetrical structural design, this absorber exhibits outstanding polarization stability and retains highly efficient absorption across a broad range of incident angles spanning from 0° to 60°. Therefore, this absorber demonstrates tremendous prospects in cutting-edge fields such as terahertz imaging, terahertz modulation, and material inspection.
