Abstract :
The coarseness error inherent in a TLM simulation involving sharp edges is reduced by increasing the speed of pulse propagation around the discontinuity with only a local mesh modification. The implementation of the technique is described in detail and the method is applied to a narrow band E-plane filter.<>
