Eigenmode hybridization enables lattice-induced transparency in symmetric terahertz metasurfaces for slow light applications

Traditional lattice-induced transparency demonstrations are activated by varying the meta-atom lattice constant such that the plasmonic and lattice modes interfere. Here we report on the observation of enhanced coupling between two eigenmodes (first- and second-order) by varying the lattice ...
