Changing simulation medium

Hello,

can you somehow define simulation material without defining specific 3D model? I wanted to simulate antenna beneath the earth to make a scenario with  "infintie" burial dimensions. I kept using sommerfeld integrals from Construct->Structuers->Planes/arrays->Plane/ground.

Basically is there anyway to fill "white space" (which im assuming is free space with epsilon 1) with specific medium without defining "Big cuboid" with specific material.

    Hi Gracjan,

    Not sure if thiy is what you're looking for, but you may change the properties of the "free-space":

    Hi Gracjan,

    the space at Z <= 0 is the material you defined, as indicated by the arrows facing downwards, space at Z > 0 is free space. I think that for better visability just the plane is colored.

    Please be aware that the directivity of the antenna will be different to the "Big Cuboid" solution at low theta angles, since the Sommerfeld equation is 0 in the XY plane.

    Best regards,
    Volker
