“…A similar duct problem has already been stated by Noble [11] and is solved by Morse and Feshbach [12]. In the similar context Büyükaksoy and Tayyar [13] studied the scattering problem at the junction of perfectly conducting and impedance parallel plate waveguide having different impedances of lower and upper plates. Tayyar et al [14] studied parallel plate waveguide problem using opposing rectangular dielectric-filled grooves.…”

In this paper, we have made Wiener-Hopf analysis of an acoustic plane wave by a semi-infinite hard duct that is placed symmetrically inside an infinite soft/hard duct. The method of solution is integral transform and Wiener-Hopf technique. The imposition of boundary conditions result in a 2 × 2 matrix Wiener-Hopf equation associated with a new canonical scattering problem which is solved by using the pole removal technique. In the solution, two infinite sets of unknown coefficients are involved that satisfy two infinite systems of linear algebraic equations. These systems of linear algebraic equations are solved numerically. The graphs are plotted for sundry parameters of interest. Kernel functions are also factorized.

This article deals with the propagation of fundamental plane mode in pentafurcated waveguide structure with soft-hard boundaries. Three semi-infinite ducts are located inside an infinite waveguide. In particular, we aim to find the reflected field amplitude for the underlying problem by using the standard mode-matching approach. We also present some numerical illustrations by determining the reflected field amplitude for different dimensions of the pentafurcated waveguide structures. Such investigations are useful in the reduction of noise effects generated through variety of mechanisms.
