Abstract
We present and compare three time domain algorithms for calculating the dispersion characteristics of transmission lines of
arbitrary cross-section : the 2-DV FD-TD, the Complex SCN TLM and the 2-DV SCN TLM proposed in this work. All the algorithms
prove efficient, as a result of reducing the numerical analysis to two space dimensions. Their accuracy is demonstrated by
means of comparison with the results obtained by other methods, for a range of practical examples of microwave guiding structures.
We also introduce a new type of excitation which further improves the efficiency and reliability of the time-domain approach.
