Hi,

I am trying to study a scenario of infinite domain half-space that is separated by infinite anisotropic conductive sheet. The excitation is coming from a dipole. My problem is in defining the anisotropic conductive sheet. Can you suggest what is the best method for implmenting this?

A picture is available in this link image

Thanks

I'm trying to understand the image you posted. It seems that your anisotropic conductive sheet is in the XY plane, but that you want it to be conductive in (only?) the Z direction. Is that what you meant? Or might you actually be interested in modeling something like a polarizing material that is conducting (for example) in only the X direction? You mentioned including a dipole excitation. What is the orientation of your dipole?

Dear Robert,

The conductive sheet is in the x-y plane. The dipole excitation is z-directed and placed above the sheet. The media above and below the sheet are free-space. The structure extends to infinity in all directions. I am having difficutly in modeling the anisotropic sheet electrical conductivity which is described as a complex tensor. I intend to use frequency domain solution at a single frequnecy.

Thanks
