Abstract

The method of lines (MoL) and discrete mode‐matching (DMM) method were originally applied to problems with separable boundaries and lateral homogeneity (for instance, layered planar structures). Since then, these methods have been directly applied to structures with non‐separable boundaries and/or lateral inhomogeneity. Although these extensions can be justified in certain approximate cases, there has not been sufficient discussion on its mathematical foundation. This paper discusses the above extensions and shows that the direct application of these methods to general problems may lead to inaccurate and even incongruous results. © 2003 Wiley Periodicals, Inc.

Most traditional theories of speech production are currently based on plane waves. However, it is well known that, for acoustic waveguides, higher acoustical modes start to propagate and can become predominant above cut-on frequencies. This paper thus presents the transmission line matrix method, a

This paper is concerned with the application of model reduction methods, which are popular for linear systems, to systems with local non-linearities, modelled by using finite element analysis. In particular these methods are demonstrated by obtaining the receptance of a continuous system with cubic
