Fourier modal method for perturbation analysis of bound states in the continuum
Nan Zhang, Ya Yan Lu
Bound states in the continuum (BICs) supported by periodic photonic structures are surrounded by high- resonances and serve as centers of polarization vortices in momentum space…
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(…
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…
Local Robustness of Bound States in the Continuum through Scattering-Matrix Eigenvector Continuation
Ya Yan Lu, Jiaxin Zhou
We consider the diffraction of time-harmonic plane waves by a periodic structure, governed by the Helmholtz equation. Bound states in the continuum (BICs) are quasi-periodic fields…
An efficient numerical method for simulating two-dimensional non-periodic metasurfaces
Fuhao Liu, Ya Yan Lu
Metasurfaces are extremely useful for controlling and manipulating electromagnetic waves. Full-wave numerical simulation is highly desired for their design and optimization, but it…
