 This paper proposes a new method for creating Brillouin zone folding induced bound states in the continuum, BZF-BICS, which can be used to create resonant cavities with extremely high quality factors. The authors demonstrate that these bics have a much higher quality factor than traditional bics, and they are also more resistant to structural disorder. This makes them ideal for use in Terahertz devices, quantum computing, and photonic integrated circuits. This article was authored by Wenhao Wang, Yogesh Kumar Srivastava, Thomas C.
