Abstract
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....

Summary
A major concern in the developed world is how to reduce structural vibration, and harmful and unwanted noise in many technical and industrial complicated devices. Different types of structures have been considered by Lawrie and colleagues[2,3,4] where mode-matching technique is applied to get solutions there by developing new orthogonality relations. Ammari et al.[6] presented the scattering of electromagnetic waves by a thin dielectric planar structure They described the a method which can be viewed as a computational approach that potentially simplifies scattering calculations for problems involving thin scatterers. Ammari et al.[7] have developed a solution to the problem of reconstructing the spatial support of noise sources from boundary measurements using cross-correlation techniques. They discussed the case where the noise sources are spatially correlated
