Adding a metallic card in EDITFEKO

In the attached editfeko file I would like to change the material property of a defined wire antenna from PEC to Copper. I added the following lines after the EG card.

DI: copper : -1 : 3 : : : : 1 : 58130000 : 0
ME: copper

When I open the postfeko file after running the simulation the wire antenna is still defined as PEC. Can you please have a look at the attached .pre file and let me know how to assign the material correctly.

    Hi @Shan25

    The ME card is used for regions, not for wires. To change the material of a wire, you can use the SK card. For this it also makes sense not to give each wire a single label (LA card), but to group them together. I assigned three labels in steve_best_modified_alt.pre: "wire", "leg" and "feed". The wires with label "wire" and "leg" then get assigned copper in the two SK cards.

    Hope this help!

     

    Best regards,

    Torben
