The paper proposes an ultra-narrow band graphene refractive index sensor, consisting of a
patterned graphene layer on the top, a dielectric layer of SiO2 in the middle, and a bottom …

Based on the selective excitations of the forward and backward propagating resonant
guided modes, we achieve dual bound states in the continuum (dual BICs) in a compound …

In recent years, the concept of bound states in the continuum (BICs) in metasurfaces has
become a research focus, providing an important physical mechanism for engineering high …

Recently, based on the selective excitation of the guided mode, researchers realized quasi-
bound states in the continuum (quasi-BICs) in all-dielectric compound grating waveguide …

We propose a graphene-dielectric hybrid metamaterial (GDHM) that supports the quasi-
bound state in the continuum (BIC). By rotating one of the LiTaO 3 bars, the quasi-BIC …

Chiral quasi-bound states in the continuum (QBIC) offer novel mechanisms to achieve
intrinsic chiroptical responses. However, current studies on chiral QBIC metasurfaces are …

Bound states in the continuum (BICs) have drawn fundamental and technological interests
due to their distinct features such as infinite quality factor and extremely localized fields …

High-Q resonances in metasurfaces, stemming from symmetry-protected bound states in the
continuum (BICs), have proven to be effective for achieving high-performance optical …

Terahertz logic gates play a crucial role in optical signal processing and THz digitization. In
this paper, we propose a design strategy for graphene-based metamaterial THz all-optical …

The Fano profile inspired by bound states in the continuum (BICs) has emerged as an
effective approach to obtain high quality factor (QF) resonances. However, achieving …
