Abstract

Guided modes may exist on periodic structures above the lightline, and they are called bound states in the continuum (BICs). For BICs on a 1D periodic array of circular cylinders, we show that the BICs disappear and become resonant modes when the cylinders are slightly distored so that the reflection symmetries are broken.
