Time domain for pulse propagation

Hello

I use an electrical dipole as source excitation in the frequency range of 200Hz-200kHz. I ask in postfeko time domain calculating using double exponential pulse.

I observed the near electrical and magnetic field in one plan in time domain so the Magnetic field is correct but the electrical field contains a very high DC components. I tried a lot configuration to srt the right parameters (frequency range vs time domain) but I never obtained a correct results.

Could you please help me to understand why this wrong result only for E field in time domain

Feko does not do static analysis and thus the DC components are estimated.

Results could differ based on the lowest frequency simulated.

You could try to simulate from a lower frequency.

Also make sure you are using Feko 2018 or later where options for the DC estimation was added/improved. This is accessed as seen below.
