WebFor observing high-Q quasi-bound states in the continuum (BIC), the metasurfaces should be made of high-index materials, restricting their applications due to the limited material functionalities.In this work, we demonstrate that high-Q quasi-BIC can also be obtained by using lower-index dielectrics, provided that the metasurfaces are supported … 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 conventional wisdom.
What is a simple example of bound state in the continuum?
WebBound states in the continuum (BICs) are a special kind of spatially localized states with the corresponding frequencies lying in the continuous spectrum. The existence of such … Bound state in the continuum (BIC) - is an eigenstate of some particular quantum system with the following properties: 1. Energy lies in the continuous spectrum of propagating modes of the surrounding space; 2. The state does not interact with any of the states of the continuum (it cannot emit and cannot be excited by any wave that came from … ku rindukan kau hadir disini lirik

WebApr 20, 2024 · Bound states in the continuum (BICs) have attracted a great deal of interest very recently, due to its unique way to enhance light-matter interactions and manipulate wave behaviors [1, 2].These states remain localized even though they are embedded in the continuum of extended states, sometimes referred to as embedded … Optomechanical crystal with bound states in the continuum. Nature communications , 13 (1), 1-7. 在[1]中，我们将光子晶体中的BIC自然而然地推广到声子晶体（弹性波），实验上通过叉指换能器（Interdigital transducer, IDT）产生的声表面波探测到了声子晶体中的BIC。 See more 事实上在上面的Nature实验文章中，作者们已经试图给这些Accidental BIC一个解释：如下图所示，对于Band在布里渊区的每一个模式 (\omega,k_x,k_y) ，我们都可以把这个模式耗散出的平面波的两个偏振分量 c_s 和 c_p 提取出来 … See more 从仿真的角度上看，光子晶体中的BIC只是在特殊参数下光子晶体模式的一种特殊表现，所以仿真方法和普通Unit cell仿真没有区别。我们这里选用的系统参数以中接近Merging的情况（晶 … See more 我们这里大概梳理一些（我所了解的）从光子晶体平板中的accidental BIC在实验上被发现、理论上被解释之后的重要工作和领域发展概况。这里没有采取时间顺序，而采取列表的方法进行梳理，实因作者能力有限。（写到这有种要虎头 … See more Web一定要..; 有义务; 注定，必定.
