Experimental observation of photonic nodal line degeneracies in metacrystals
Nodal lines are 1D band crossings forming a ring in the Brillouin zone which can spawn Weyl points. Here, using a cut-wire metacrystal designed for gigahertz frequencies, Gao et al. observe photonic nodal line degeneracies as well as the photonic Weyl points arising from them.
