Optical bound states in the continuum in metallic gratings with compound lattices
Bound states in the continuum (BICs) are completely localized modes with no radiation but
existing within the continuous spectrum of radiating waves. In photonic crystals, accidental …

The suppression of finite size effect within a few lattice sites
Boundary modes localized on the boundaries of a finite-size lattice experience a finite size
effect (FSE) that could result in unwanted couplings, crosstalks and formation of gaps even …
