Three-dimensional Dirac semimetal metamaterial enabled by negative couplings

Three-dimensional (3D) semimetals with fourfold degenerate Dirac points are of prominent importance in topological photonics as the parent states to Weyl nodes, line nodes, & etc. The dispersions on all the momentums’ directions are linear, which represents that the Dirac point and topologically...
