For a 2D metal antenna, the function
returns the current at the middle (centroid) of each 3-sided facet, which I believe is the vector sum of the current flowing across each of the facet's 3 edge segments. As such, i is an average value.
Is there a way to obtain each facet's segment currents individually, instead?
I'm not interested in the vector sum. The Matlab built-in function currentm() appears to be locked.
