摘要：A bound state in the continuum (BIC) is a localized or guided eigenmode that does not couple with radiation waves propagating to or from infinity. For photonic systems, a periodic structure sandwiched between two homogeneous media is the most popular platform for observing BICs and realizing their applications. Since a BIC can be regarded as a resonant state with an infinite quality factor, it is possible to realize resonant states with extremely high quality factors by perturbing the structures or varying the Bloch wavevector. Due to their unusual properties, BICs are useful in a number of applications. In this talk, I will present the basic mathematical theory and numerical computations of BICs on periodic structures.
