The effects observed by a moving source and stationary receiver, or conversely stationary source and moving receiver are well known to physicists. The Doppler effect as it is commonly known is recognized as a perceived change in frequency of the inci

The numerical simulation of wave propagation in bounded space using differential-based models generally encounter spatial discretisation problems when the boundaries of the computation space do not fall on exact multiples of the models discretisation

Transmission line matrix (TLM) schemes for the Laplace equation exhibit some curious features. There exist values of TLM parameters where convergence towards the analytical values is very rapid. This phenomenon is first examined using a binary scatte

In previous work novel, techniques with general applications were used to define the transmission line parameters within two- and three-dimensional orthogonal curvilinear meshed space. This paper presents a specific application of the technique and d

The signals obtained at each time step of a transmission line matrix (TLM) simulation of Gaussian diffusion are analysed for two- and three-dimensional cases. A combinatorial formula is derived to provide the signal magnitude at any spatial position

In this article a method of curvilinear orthogonal mesh generation in three dimensions is described. This technique is based on the solution of elliptic equations in two and three dimensions. Frequently, the generated meshes are not quite orthogonal;

The scattering of sound from surfaces by rotating sources such as the tips of helicopter rotor blades can be used as a method of locating and ranging obstructions which may represent a physical danger to the craft. Modelling such systems presents som

Transmission line matrix (TLM) algorithms for lossy electrical network provide a solution for the telegrapher's equation. In spite of the fact that these constitute a lossy wave equation analogue, they have been successfully used to model thermal pro
