This article examines the dispersion characteristics and energy distribution in different
regions of the bifurcated waveguide with vertical step discontinuities. In this research study …

Present communication addresses the scattering of the dominant acoustic wave mode
propagating from a semi-rigid waveguide. The underlying waveguide is tuned because of …

The present research focuses on the study of how acoustic radiation modes behave in an
elastic shell that has trifurcated junctions and structural variations. To express the vibration …

Researchers in applied mathematics, physics, and engineering are investigating how to
reduce unwanted or ravage noise to an acceptable level. This article describes a trifurcated …

The present communication addresses the reflection and transmission analysis of a two-
dimensional waveguide structure with planar and non-planar surfaces. In the fields of …

The strong potential of porous media to absorb and change an incident sound wave
interacting with a fluid that fills the pores of the material has sparked interest in their acoustic …

This research article investigates the behavior of elastic waves in an inhomogeneous
isotropic three-layered sandwich plate with soft-core and stiff-skin layers embedded in …

Analyzing the attenuation of unwanted sound in waveguides or ducts has led to many
complex, interesting and challenging problems for engineers and researchers. The …

This study investigates the propagation of fluid–structure coupled waves in a duct featuring
both rigid and flexible interfaces. Two cases are considered: in the first case, with a rigid …

This communication is devoted to the analysis of the energy flux of a two-dimensional
waveguide with planar and non-planar surfaces. The main goal is to analyze the effects of …
