Abstract
A free space boundary for the TLM modelling of acoustics is described. This is a development of the one-way wave equation method devised for finite difference time domain models, and absorbs energy over a wide range of incident angles. Comparisons with the matched termination method and with an ideal ´infinite´ mesh are presented.
