Plasma absorption levelling by phase coherence in meta-surface stacked structure
Xing-Yu Xu, Zhong-Zhu Liang, Li Qin +1
In this paper, we propose a MIM (metallic metasurface-insulator-metal) stacked structure to realize perfect absorption in mid- and far- infrared bandwidth. A large number of metall…
