Note: Plotting Magnetic current in HFSS-IE is relatively simple. It is M = Exn on an interface between two non-conducting materials. This is an equivalent current. Plotting Electric current in HFSS-IE involves three cases:

J = nxH on a surface of solid conductor (H is zero inside the conductor). This is a TRUE physical current.
J = nx(H1-H2) on a conducting sheet which is inside a region/background (or it is not an interface between two regions). This is a TRUE physical current.
J = nxH1 on a conducting boundary between two regions (it doesn't matter if the two regions have the same material). H1 is the field on the positive side of the surface. However, if region 2 is the background, we will display J = nxH2. This is an equivalent current.
