Terahertz (THz) technology offers unparalleled opportunities in a wide variety of
applications, ranging from imaging and spectroscopy to communications and quality control …

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 …

Here, we propose a scheme to further reduce scattering losses and improve the robustness
of symmetry-protected bound states in the continuum (BICs) by decreasing the radiation …

Oligomer metasurfaces have attracted a lot of attention in recent years because of their
ability to drive strong resonance effects. In this work, by perturbing the symmetry of the …

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 …

Multiple modes resonance provides the possibility of broadband filtering and has great
potential applications in terahertz devices, including miniaturized spectrometers …

Bound state in the continuum (BIC) refers to the trapped state in the radiation continuum of a
system. In the terahertz band, BIC provides a unique and feasible method to design devices …

Resonances with both high-quality factor and polarization-independent characteristics are
highly desirable for terahertz (THz) sensing. Here, THz sensors based on asymmetric …

Herein, we propose an all dielectric, open-slit, U-shaped resonant arm-based metasurface
that achieves three bound states in the continuum (BIC) in the high-frequency terahertz band …

In recent years, bound states in the continuum (BICs) have attracted attention of researchers
because they are located above the light cone without leakage and have infinite lifetimes. In …
