Time Domain Analysis Using TimeFEKO

— filed under: ,

Brief description on how TimeFEKO can be used to get time-domain information from FEKO.

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 automated by the TimeFEKO module.

Available Pulse Forms

  • Gaussian

  • Ramp

  • Double exponential

  • Triangle.

Example:

The time domain response of the mono-static scattered electric field (Ez) is to be determined for a Gaussian pulse illuminating a cube along the x-axis.

Surface currents at 250 MHz. Time domain response of the incident
and the scattered field.
