Abstract :
A novel technique for arbitrary boundary positioning in transmission line matrix (TLM) networks is described. This capability removes the restriction that dimensions of TLM models can only be integer multiples of the mesh parameter, and allows superior boundary resolution. Since the position of boundaries can be continuously varied even during a simulation, this feature can model moving boundaries for time domain optimization and phenomena such as the Doppler effect.<>
