Multi-functional resonant acoustic networks for wave routing
Olivier Richoux, Vassos Achilleos, Georgios Theocharis +2
We demonstrate that asymmetric 3-port devices can be used to design a multi-functional set-up operating as a symmetric combiner and splitter at the same frequency. For a concrete i…

Subwavelength Interferometric Control of Absorption in Three-port Acoustic Network
O. Richoux, V. Achilleos, G. Theocharis +1
Utilizing the effect of losses, we show that symmetric 3-port devices exhibit coherent perfect absorption of waves and we provide the corresponding conditions on the reflection and…
