Accessing the exceptional points of parity-time symmetric acoustics

Parity-time phase transition and exceptional points contribute to the design of many components, but are hard to access due to the dispersive nature of the required materials. Here, the authors introduce a method to systematically control acoustic parity-time phase transition through an active eleme...
