Parametric dependence of bound states in the continuum: a general theory
Amgad Abdrabou, Lijun Yuan, Wangtao Lu +1
Photonic structures with high- resonances are essential for many practical applications, and they can be relatively easily realized by modifying ideal structures with bound stat…

Real transmission and reflection zeros of periodic structures with a bound state in the continuum
Lijun Yuan, Mingyang Zhang, Ya Yan Lu
For lossless periodic structures with a proper symmetry, the transmission and reflection spectra often have peaks and dips that are truly and , respectively. The full…

Approximating transmission and reflection spectra near isolated nondegenerate resonances
Hongyao Wu, Lijun Yuan, Ya Yan Lu
A linear scattering problem for which incoming and outgoing waves are restricted to a finite number of radiation channels can be precisely described by a frequency-dependent scatte…
