DOI: 10.1002/adom.202501139

Abstract: Photonic bound states in the continuum (BICs) are nonradiative resonances embedded in the radiative spectrum of a system, resulting from the complete cancellation of all radiative channels. In absence of material losses, their infinite lifetime… read more here.
