Simultaneous Realization of Coherent Perfect Absorber and Laser by Zero-Index Media with both Gain and Loss
Ping Bai, Kun Ding, Gang Wang +5
We investigate a unique type of zero-index medium with both gain and loss (ZIMGL), whose effective permittivity and permeability are purely imaginary and of opposite signs. We show…

Pseudo-time-reversal symmetry and topological edge states in two-dimensional acoustic crystals
Jun Mei, Ze-Guo Chen, Ying Wu
We propose a simple two-dimensional acoustic crystal to realize topologically protected edge states for acoustic waves. The acoustic crystal is composed of a triangular array of co…
