的COMSOL交流群,发现虽然好久好久没看群,群里还是有很多童鞋在问关于BIC(连续体束缚态,Bound-states In the Continuum)的问题,足可说明大家对BIC这一独特物理现象的兴趣。其实相较许多领域来讲,BIC的门槛不算高,不过毕竟是小白入门,在这之中还是会遇到很多的问题。本文旨在从四个方面介绍连续体束缚态BIC:概述、物...
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 conventional wisdom. Although BICs were first proposed in quantum mechanics, they are a general wave ...
Trapping electromagnetic waves within the radiation continuum holds significant implications in the field of optical science and technology. Photonic bound states in the continuum (BICs) present a distinctive approach for achieving this functionality, offering potential applications in laser systems, sensing ...
Photonic bound states in the continuum (BICs) are eigenmodes with an infinite lifetime, which coexist with a continuous spectrum of radiating waves. BICs are not only of great theoretical interest but also have a wide range of practical applications, e.g. in the design of optical resonators....
《Zero-Index Bound States in the Continuum》是2018年发表在PHYSICAL REVIEW LETTERS上的一篇文章,第一作者为Momchil Minkov。这篇文章主要讲述了如何在连续谱束缚态(BIC)中通过偶然简并得到位于布里渊区中心Γ点的狄拉克锥,实现低损耗的等效零折射率材料。 在具有等效

Dual bound states in the continuum enhanced second harmonic generation with transition metal dichalcogenides monolayer Dual bound states in the continuum enhanced second harmonic generation with tra…
Bound states in the continuum (BICs) defy conventional wisdom that assumes a spectral separation between propagating waves, that carry energy away, and spatially localized waves corresponding to discrete frequencies. They can be described as resonance states with infinite lifetime, i.e., leaky modes...
When two nonorthogonal resonances are coupled to the same radiation channel, avoided crossing arises and a bound state in the continuum (BIC) appears with appropriate conditions in parametric space. This paper presents numerical and analytical results on the properties of avoided...
Bound states in the continuum (BICs) are ubiquitous in many areas of physics, attracting special interest for their ability to confine waves with infinite lifetimes. Metasurfaces provide a suitable platform to realize them in photonics; such BICs are remarkably robust, being however complex to tune...
