Abstract
We proposed that the introduction of toroidal-assisted response can address a state-of-the-art transmission efficiency of plasmonic metasurfaces. The advantage of Fano coupling between toroidal dipole and toroidal quadrupole enables a giant cross-polarization converter with a transmission efficiency of 22.9% in a single-layer plasmonic metasurface comparable to the theoretical bound. While a hybrid plasmonic meta-atom can be used to realize toroidal-assisted generalized Huygens’ sources for forward radiation enhancement, thus achieving a transmission efficiency beyond 50% at the near-infrared region.
