Abstract: Topological manipulation of sound has recently been a hot spot in acoustics due to the fascinating property of defect immune transport. To the best of our knowledge, the studies on one-dimensional (1D) topological acoustic systems… read more here.

Abstract: On dielectric periodic structures with a reflection symmetry in a periodic direction, there can be antisymmetric standing waves (ASWs) that are symmetry-protected bound states in the continuum (BICs). The BICs have found many applications, mainly… read more here.

DOI: 10.3788/col202523.053601
Abstract: In this paper, we propose a new strategy based on the interconversion between two symmetry-protected bound states in the continuum (SP-BICs) to break the high symmetry dependency of the SP-BIC. The excitation of four high-Q… read more here.
