- Acoustic spoof surface waves are supported at the interface between a fluid and a corrugated rigid plate, and their dispersion is very sensitive to minute changes in the fluid parameters. Relying on this distinct feature, we design and numerically analyze the acoustic analogue of a Mach-Zehnder interferometer based on acoustic spoof surface waves, and demonstrate its potential for sensing of binary gas mixtures. The design procedure of the Mach-Zehnder gas sensor is presented, together with the structure response for different concentration of carbon monoxide in CO/air mixture, confirming the high sensitivity of the proposed structure.
