how can I model a two layered conductor wire in order to study the skin effect at higher frequencies

supposes a thin copper layer covering an aluminum conductor core. is it possible to use the wire model in feko? or I should use the cylindrical model? how can I do it?

    You won't be able to use the wire model for this kind of problem (the wire core can be any metal but only dielectric coatings can be applied on it). So, you would need to go with the cylinder model.

    For a proper modeling of this setup using cylinders, make sure you union the two cylinders and set both the region medium to free space. Then, change the face medium property of the inner cylinder to Aluminum and specify a thickness that is greater than the skin depth. Next, change the face medium properties of the outer layer to copper and specify the desired thickness (which is equal to the coating thickness).
