Photonic zero-energy modes in a metal-based Lieb lattice
We design a photonic tight-binding system using the dispersive background, and observe the noncompact photonic zero-energy modes for both monopole and dipolar states in a finite Lieb lattice with flat truncations. In such a photonic Lieb system, the compact localization of s , p , and d flat bands i...
