Acoustic Splitter Waves Based on Ramified System Made of Waveguides

Séparateur d'ondes acoustiques basé sur un système ramifié composé de guides d'ondes

Résumé

In this paper, we studied the propagation of acoustic waves in an acoustic ramified system. Our proposed system contains an input waveguide of length d0 and three output lines (three channels), each output line contains a semi-infinite waveguide. The theoretical analysis is based on the Transfer Matrix Method (TMM), which allows us to calculate the three transmission rates T1, T2, T3 and the reflection rate R. We demonstrate that our proposed three-output channels system can be used to design a multifunctional device that functions as an amplitude splitter: an incident sound wave is splited to three output channels. This system is capable of achieving various waveguiding characteristics with perfect channels transmissions.
