A fast spatial domain method for the suppression of excitation-induced spurious modes in SCN-TLM

A fast method for the suppression of excitation-induced spurious modes in the Transmission Line Matrix (TLM) method is presented for the symmetrical condensed node (SCN) scheme. The method of spurious-free excitation allows for a coarser mesh discretization improving the effectiveness of the TLM-simulation. The capability of the method is demonstrated by way of an example.
