Ring bound states in the continuum with broken time-reversal symmetry

Year: 2025

Type: article

Abstract: -space and analyze the forming mechanism. The ring BICs provide a special response of spatial directions and can be modulated by multiple structural parameters. Different from the linear polarizations of far-field from general BICs, the far-field polarizations within the ring qBICs are either ideally circular polarization or elliptical polarizations with all potential values of ellipticities leading to infinite density of states. The ring qBICs allow us to manipulate the polarization with more degrees of freedom for potential applications.
