In this work, the acoustic transfer matrix for a cylindrical dissipative silencer of arbitrary cross-section and bulk-reacting lining is derived for the case of negligible mean #ow. The derivation is performed in a two-step procedure. First, the corresponding in"nite-lined duct is analyzed by separa

✦ Synopsis
The author is to be congratulated for his straightforward solution of this important technical problem [1]. It is also the prupose of this discussion to bring the attention of the interested reader to additional references regarding use of the point-matching method in vibrations and acoustics problems.
H. D. Conway employed the methodology when dealing with field and eigenvalue problems within the realm of the classical theory of plates [2,3]. It is important to point out that the governing partial differential equation of a vibrating plate is

## Communicated by F. Ursell This article establishes the existence of trapped-mode solutions of a linearized water-wave problem. The fluid occupies a symmetric horizontal channel that is uniform everywhere apart from a confined region which either contains a thin vertical plate spanning the depth
## Abstract In this article, we consider the propagation problem inside a waveguide filled with a homogeneous bi‐isotropic material. The cross section of the waveguide is assumed arbitrary. By using the classical theory for the 2D Helmholtz equation in the cross section and the null‐field approach,
## Abstract The aim of this communication is to correct potential misunderstandings about the PMLs (which are called the MIPMLs) based on __D__–__H__ (__E__–__B__ or __D__–__B__) fields. In fact, the motivation for developing the MIPMLs is to establish accurate and efficient PML absorbers for gener
