WebOptical bound states in the continuum (BIC) are topological singularities of the scattering matrix, known for their unique light-trapping capability and enhanced light–matter … WebJun 29, 2024 · Bound states in the continuum (BICs) have received increasing attention from researchers because of their potential applications in photonic crystal fibers, as well as in lasing, sensing, and surface …
WebIn general, valley edge states that exhibit unidirectional propagation and are immune to defects and disorders could be realized at the interface between two valley photonic crystals with opposite valley Chern numbers. Herein, by merging the physics of valley edge states and bound states in the continuum, we propose and numerically demonstrate ... WebJul 19, 2016 · Bound states in the continuum (BICs) are waves that remain localized even though they coexist with a continuous spectrum of radiating waves that can carry energy away. Their very existence defies...
Webstate: a bound state in the continuum (BIC). Historically, von Neumann and Wigner [5] first proposed that a BIC can be explicitly constructed in a quantum system when the wave function exhibits weakly damped oscillations. Furthermore, the occurrence of BICs was interpreted as the interference of resonances in direct and via the continuum ... WebFeb 23, 2024 · The topological bound states are well localized around the boundaries of the pentagonal cores with and without hollow regions. The topological bound states immunize against the finite sizes and the moderate imperfects of plates, essentially differing from the trivial defect states. The discovery of topological bound states unveils a new …
