Diffraction of acoustic plane wave through a semi-infinite hard duct which is placed
symmetrically inside an infinite soft/hard duct has been analyzed rigorously. Convective flow …

We have considered the problem of radiation of sound from a semi-infinite soft duct. This
duct is symmetrically located inside a hard but infinite duct. The problem is solved when the …

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 …

The radiation of sound waves from partially lined duct is treated by using the mode-matching
method in conjunction with the Wiener-Hopf technique. The solution is obtained by …

In this study, we analyzed the diffraction of the acoustic dominant mode in a parallel-plate
trifurcated waveguide with normal impedance boundary conditions in the case where …

In this study, the propagation of a fundamental plane mode in a bifurcated waveguide
structure with soft–hard boundaries is analyzed by using the Helmholtz equation. The …

The diffraction of sound from a semi‐infinite soft duct is investigated. The soft duct is
symmetrically located inside an acoustically lined but infinite duct. A closed‐form solution is …

The rigorous solution describing the sound radiation by an arbitrary surface source located
at the bottom of a cylindrical open cavity embedded in a flat baffle has been obtained. The …

The paper presents the analytical description of diffraction phenomena of sound at the
opening of a two dimensional semi-infinite acoustically soft duct. This soft duct is …

The paper presents analogies between acoustic and electromagnetic wave field occurring in
limited areas, such as waveguides, when electromagnetic waves are not purely transversal …
