Experimental observation of non-Hermitian higher-order skin interface states in topological electric circuits
Bin Liu, Yang Li, Bin Yang +4
The study of topological states has developed rapidly in electric circuits, which permits flexible fabrications of non-Hermitian systems by introducing non-Hermitian terms. Here, n…

We propose to simulate 3D Dirac points and line-nodes with nontrivial topology in nonsymmorphic all-dielectric photonic-crystals with space-time reversal symmetry, which can…
Broadband perfect absorption of ultrathin conductive films with coherent illumination:Superabsorption of microwave radiation
Sucheng Li, Jie Luo, Shahzad Anwar +7
Absorption of microwave by metallic conductors is exclusively inefficient, though being natively broadband, due to the huge impedance mismatch between metal and free space. Reducin…
