On the Robustness of Propagating Bound States in the Continuum
Lijun Yuan, Ya Yan Lu
Bound states in the continuum (BICs) are localized eigenmodes with their frequencies in the radiation continuum of scattering states. The existence of a BIC implies the loss of uni…

Parametric dependence of unidirectional guided resonances in periodic structures
Lijun Yuan, Ya Yan Lu
Unidirectional guided resonances (UGRs) in periodic structures are special resonant modes that exhibit strict one-sided radiation, even though radiation in both sides is allowed, o…
