Abstract: We investigate the effects of fragmenting metasurfaces (MSs), composed of dielectric disks, on their electromagnetic responses and show that the presence of four abrupt boundaries between finite size structures and free space leads to the… read more here.

Abstract: The interest in high quality factor (high-Q) resonances in metasurfaces has been rekindled with the rise of the bound states in the continuum (BIC) paradigm, which describes resonances with apparently limitlessly high quality-factors (Q-factors). The application of… read more here.
