Simulation of impact of ferrite tiles used as ground absorbers for antenna measurements

Before considering using FEKO to analyse absorber materials placed on the ground of an outdoor antenna test site, I would like to ask a very basic question.
Is it possible with FEKO to analyse the difference in antenna patterns when the ground under the AUT is partially covered with e.g. ferrite tiles, "normal" soil or conductive aluminium plates? The VHF/UHF AUT shall be a quadfilar helix antenna pointing to the sky. The near-field of the AUT shall be scanned along a planar horizontal surface above the antenna. As the free-space pattern is to be measured, any ground coupling effects (e.g. from the AUT's near-field backlobe) shall be "sufficiently" (to be analysed) suppressed by the use of ferrite tiles as ground absorbers. Any advice on how to achieve these analyses with FEKO would be very welcome.

    Hi Torsten,

    Of course you can simulate different ground scenarios in Feko and compare the results (I had already sent you an example ~2 months ago). Please excuse that nobody has reacted here in the forum for such a long time.

    Best regards,
    Torben
