TLM time-domain modelling and the use of windowing profiles for frequency-domain transformations applied to microwave cavity resonators

摘要

This paper presents developments made to the TLM method in the time to frequency-domain transformation of the impulse response solution. An improvement to the technique by which the three-dimensional TLM time-domain method is post-processed is presented. It is shown that the selective choice of a particular data windowing profile plays a significant role in the accuracy of the results, clarity of output response and the extraction of the S-parameters.
