Controlling light absorption of graphene at critical coupling through magnetic dipole quasi-bound states in the continuum resonance
TL;DR: In this article, a quasi-BIC resonance was proposed to control light absorption at critical coupling through the quasi BIC resonance, and the maximum absorption of 0.5 was achieved when the radiation rate of the magnetic dipole resonance equals to the dissipate loss rate of graphene.

Free switch between bound states in the continuum (BIC) and quasi-BIC supported by graphene-metal terahertz metasurfaces
Jitao Li,Jie Li,Chenglong Zheng,Zhen Yue,Silei Wang,Mengyao Li,Hongliang Zhao,Yating Zhang,Jianquan Yao +8 more
TL;DR: In this article, the free switch between BIC and quasi-BIC is successfully achieved by introducing the structured graphene into the metal terahertz metasurfaces, which is based on free-electron concentration of graphene changing from semiconductor-like to metal-like with adjustment of Fermi energy.

Resonance Switchable Metamaterials Using MEMS Fabrications
Wu Zhang,Weiming Zhu,Hong Cai,Ming Lin Julius Tsai,Guo-Qiang Lo,Din Ping Tsai,H. Tanoto,Jinghua Teng,Xinhai Zhang,Dim-Lee Kwong,Ai Qun Liu +10 more
TL;DR: In this paper, a switchable metamaterial working at terahertz (THz) regime was realized by using MEMS fabrications, where the resonance induced by 2.60-THz incidence was switched by reconfiguring the metammaterial element, which was analyzed using the coupled oscillators model.

Tunable anisotropic absorption in monolayer black phosphorus using critical coupling
TL;DR: In this paper, a monolayer black phosphorus (BP)-based metamaterial structure for tunable anisotropic absorption in the mid-infrared was proposed, which achieved the high absorption efficiency of 99.65% for TM polarization, while only 2.61% for TE polarization due to the intrinsic anisotropy of BP.
