Structural perturbation theory for bound states in the continuum via bifurcation of zeros and extrema of the dispersion relation
Lijun Yuan, Ya Yan Lu
In a lossless periodic structure, a bound state in the continuum (BIC) corresponds to a real zero and a local maximum of the imaginary part of a complex dispersion relation $k = k(…
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…
Parametric dependence of bound states in the continuum in periodic structures: vectorial cases
Lijun Yuan, Ya Yan Lu
A periodic structure sandwiched between two homogeneous media can support bound states in the continuum (BICs) that are valuable for many applications. It is known that generic BIC…
On the robustness of bound states in the continuum in waveguides with lateral leakage channels
Lijun Yuan, Ya Yan Lu
Bound states in the continuum (BICs) are trapped or guided modes with frequencies in radiation continua. They are associated with high-quality-factor resonances that give rise to s…
Conditional robustness of propagating bound states in the continuum on biperiodic structures
Lijun Yuan, Ya Yan Lu
For a periodic structure sandwiched between two homogeneous media, a bound state in the continuum (BIC) is a guided Bloch mode with a frequency in the radiation continuum. Optical…
Resonant field enhancement near bound states in the continuum on periodic structures
Zhen Hu, Lijun Yuan, Ya Yan Lu
On periodic structures sandwiched between two homogeneous media, a bound state in the continuum (BIC) is a guided Bloch mode with a frequency within the radiation continuum. BICs a…
