Multi-mode resonance of bound states in the continuum in dielectric metasurfaces
Bound states in the continuum (BIC) represent distinct non-radiative states endowed with infinite lifetime and vanishing resonance linewidth. Introducing asymmetric perturbation to the system can convert true BICs into h…

Tuning Metasurface Dimensions by Soft Nanoimprint Lithography and Reactive Ion Etching
Metasurfaces are ultrathin and flat layers of subwavelength nanostructures composed of metallic or high-refractive-index materials. They can alter lightwave properties effectively and show significant application potenti…
