Abstract :
This paper describes a new algorithm for the frequency-domain TLM (FDTLM) method. The conventional 12-port symmetrical condensed node (SCN) utilized in the past to construct the FDTLM algorithm is decoupled into a pair of independent 6-port nodes. Based upon the properties of decoupled nodes, a new decoupled algorithm for the entire FDTLM network is derived. As a result of this, the memory space requirements of the FDTLM is reduced significantly and the savings in CPU-time is more than 50 per cent.<>
