Substrate-engineered tunable bound states in the continuum and directional radiation in dielectric metasurfaces
Hao Song, Yanming Sun, Jian Li +2
Tunable bound states in the continuum (BICs) in metasurfaces offer powerful opportunities to control light-matter interactions, yet the role of out-of-plane symmetry breaking remai…
Manipulating reflection-type all-dielectric non-local metasurfaces via parity of particle number
Hao Song, Xuelian Zhang, Yanming Sun +1
Parity of particle number is a new degree of freedom for manipulating metasurface, while its influence on controlling non-local metasurfaces remains an unresolved and intriguing qu…
Bound state in the continuum and polarization-insensitive electric mirror in low-contrast metasurface
Hao Song, Xuelian Zhang, Jian Wang +2
High-contrast refractive indexes are pivotal in dielectric metasurfaces for inducing various exotic phenomena, such as the bound state in the continuum (BIC) and electric mirror (E…
Disorder-immune metasurfaces with constituents exhibiting the anapole mode
Hao Song, Neng Wang, Kuai Yu +2
Common optical metasurfaces are 2-dimensional functional devices composed of periodically arranged subwavelength constituents. Here, we achieved the positional-disorder-immune meta…
