Resonant mode approximation of the scattering matrix of photonic crystal slabs near several Wood-Rayleigh anomalies
arXiv:2112.05014 · doi:10.1016/j.photonics.2022.101015
Abstract
The resonant mode approximation of the scattering matrix is considered for calculating the optical properties of multilayered periodic structures within the formalism of the Fourier-modal method for two diffraction thresholds in close proximity of the spectral-angular range of interest. The developed approximation opens up possibilities for the fast calculation of the scattering matrix of these structures when describing the integral characteristics of spectra and dispersion curves containing high-Q resonances, such as bound states in the continuum.
