Multipolar origin of bound states in the continuum

, 2019
Metasurfaces based on resonant subwavelength photonic structures enable novel ways of wavefront control and light focusing, underpinning a new generation of flat-optics devices. Recently emerged all-dielectric metasurfaces exhibit high-quality resonances

Unconventional bound states in the continuum from metamaterial induced electron-acoustic plasma waves

, 2021
Photonic bound states in the continuum are spatially localised modes with infinitely long lifetimes that exist within a radiation continuum at discrete energy levels.

Simulation Analysis of Microwave Metasurface Sensing Based on Bound States in the Continuum

Photonics
High-sensitivity microwave sensing plays a vital role in material characterization and nondestructive testing, with its performance being largely determined by the quality factor (Q factor) of the sensing structure.

Active quasi-BIC optical vortex generators for ultrafast switching

New Journal of Physics, 2022
The Pancharatnam–Berry phase induced by the winding topology of polarization around a vortex singularity at bound states in the continuum (BIC) provides a unique approach to optical vortex (OV) generation.

Circularly polarized states spawning from bound states in the continuum

, 2019
Bound states in the continuum in periodic photonic systems like photonic crystal slabs are proved to be accompanied by vortex polarization singularities on the photonic bands in the momentum space.

Quasi-Bound States in the Continuum Enabled Strong Terahertz Chiroptical Response in Bilayer Metallic Metasurfaces

Crystals, 2022
Bound state in the continuum (BIC) as a novel non-radiating state of light in the continuum of propagating modes has received great attention in photonics. Recently, chiral BICs have been introduced in the terahertz regime.

Topological properties of bound-states-in-the-continuum in geometries with broken anisotropy-symmetry

, 2019
Waveguiding structures made of anisotropic media support bound states in the continuum (BICs) that arise when the radiation channel of otherwise semi-leaky modes is suppressed. Hitherto, only structures with optical axes aligned in symmetric orientations

Bound states in the continuum in periodic structures with structural disorder

Nanophotonics, 2021
We study the effect of structural disorder on the transition from the bound states in the continuum (BICs) to quasi-BICs by the example of the periodic photonic structure composed of two layers of parallel dielectric rods.

Ultrahigh Q-Guided Resonance Sensor Empowered by Near Merging Bound States in the Continuum

Photonics, 2022
Bound states in the continuum (BICs) have attracted a lot of interest in the field of nanophotonics, and provide an important physical mechanism to realize high quality (Q) factor resonance.
