Bound states in continuum
WebBound states in the continuum (BICs) are phenomena that have been predicted to exist since 1929. BICs are waves that remain perfectly confined, or bound, in an open system. Conventional waves in an open system escape, but BICs defy this norm — they stay localized and do not escape despite having open pathways to do so. WebBound State. A system of particles is said to be in a bound state if the relative motion of the particles occurs in a bounded region of space (is finite) over a period that is long …

WebMar 7, 2024 · Bound states in the continuum (BICs) have been demonstrated to be associated with topological charge and vortex polarization singularities in momentum space. WebBound state in the continuum (BIC) possessing nontrivial physical properties resembles a new physical mechanism to localize a wave within the radiative continuum . Optical BIC, an analogue of their quantum counterpart [ 20 ], provides an effective way to guide light beyond total internal reflection [ 21 – 27 ].
Web1 day ago · Optical bound states in the continuum (BICs) have enabled suppression of radiation loss in various photonic structures. However, their quality ( ) factors can be … WebApr 7, 2024 · Bound states in the continuum (BICs) can be discovered in many physical systems, for example, electromagnetic, acoustic, water, and elastic waves [1,2,3,4]. Many kinds of photonic systems have been designed to study optical BICs, such as photonic crystals [ 5 , 6 ], optical waveguides [ 7 , 8 , 9 ], graphene quantum-dot structure [ 10 ], …
In quantum physics, a bound state is a quantum state of a particle subject to a potential such that the particle has a tendency to remain localized in one or more regions of space. The potential may be external or it may be the result of the presence of another particle; in the latter case, one can equivalently define a bound state as a state representing two or more particles whose interaction energy exceeds the total energy of each separate particle. One consequence is that, given a pot… WebThe concept of optical bound states in the continuum (BICs) currently drives the field of dielectric resonant nanophotonics, providing an important physical mechanism for …
