Abstract
This article aims to investigate the mode-matching approximation of a two dimensional waveguide problem. Each of the ducts is bounded by a flexible surface of different height and, thus, the underlying eigenproblem is non-Sturm-Liouville. While developing the orthogonality relation, the corresponding problem can be solved using the mode-matching technique. The amplitudes of reflection and transmission coefficients are discussed numerically. Further, the distribution of power between the fluid regions and the flexible wall is analyzed. The truncated system is verified as it satisfies the matching interface conditions and the power balance as well.
