Multipole interference and optical sensing based on the bound states in the continuum formed in dimer metasurfaces

The all-dielectric metasurface supporting BIC based on dimer structures is proposed with the rectangular holes etched in amorphous silicon thin films. By introducing perturbations of the rotation angle of the rectangular hole as well as the difference in length and width, quasi-BIC modes in the near...
