Abstract

By exciting a broadband pulse in the time domain and performing a fast Fourier transform on the sampled time domain data it is possible to obtain the scattering parameters for a broad frequency range with one single time domain calculation. This known technique, valid for non-dispersive waveguides, is extended to homogeneously loaded dispersive waveguides. In most cases this extended technique outperforms the frequency domain approach by orders of magnitude in terms of calculation time. We will give a short introduction to this method and present some examples
