Metallic and All-Dielectric Metasurfaces Sustaining Displacement-Mediated Bound States in the Continuum
Luca M. Berger, Martin Barkey, Stefan A. Maier +1
Bound states in the continuum (BICs) are localized electromagnetic modes within the continuous spectrum of radiating waves. Due to their infinite lifetimes without radiation losses…
