Antenna facet edge (segment) currents?
2 views (last 30 days)
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.

Obtaining each facet’s current individually cannot be done using current function. As a possible workaround/solution you can increase the mesh size to get the current at many cartesian coordinates points so that the averaging won't matter. You can visualize the mesh properties of a metal or dielectric antenna or array structure by using the mesh function. Also you can use the EHFields function to calculate the E and H fields and based on the direction from E and H fields you can know what the current direction is.
