Time Domain Analysis

FEKO is based on a frequency domain formulation. Time-domain information can however be obtained by applying Fourier Transforms on broadband frequency-domain data.
The specification of time-domain pulse shapes and the required frequency domain simulations is facilitated by an interface in POSTFEKO which helps users select the appropriate pulse shape.
