Significant loss suppression and large induced chirality via cooperative near- and far-field coupling in plasmonic dimer nanoantennas
Xiaoqing Luo, Rixing Huang, Dangyuan Lei +1
Plasmonic nanoantennas containing nano-gaps support "hotspots" for greatly enhanced light-matter interactions, but suffer from inherent high losses, a long-standing issue that hind…
Polarization-independent resonant lattice Kerker effect in phase-change metasurface
Lei Xiong, Xiaoqing Luo, Hongwei Ding +2
Resonant lattice Kerker effect in periodic resonators is one of the most interesting generalizations of the Kerker effect that relates to various fascinating functionalities such a…
Broadband switchable terahertz half-/quarter-wave plate based on a graphene-metal hybrid metasurface
Xiaoqing Luo, Juan Luo, Fangrong Hu +1
Metasurfaces incorporating graphene hold great promise for dynamic manipulation of terahertz waves. However, it remains challenging to design a broadband graphene-based terahertz m…
Broadband switchable terahertz half-/quarter-wave plate based on VO2-metal hybrid metasurface with over/underdamped transition
Xiaoqing Luo, Fangrong Hu, Guangyuan Li
Dynamically switchable half-/quarter-wave plates have recently been the focus in the terahertz regime. Conventional design philosophy leads to multilayer metamaterials or narrowban…
Dynamically reversible and strong circular dichroism based on Babinet-invertible chiral metasurfaces
Xiaoqing Luo, Fangrong Hu, Guangyuan Li
We propose a Babinet-invertible chiral metasurface for achieving dynamically reversible and strong circular dichroism (CD). The proposed metasurface is composed of VO-metal hyb…
