Extracting discretized currents on a PEC surface

Hello FEKO Forum Members,

According to [1], FEKO discretizes a PEC body into multiple triangles and approximates the current on each triangle as:

$J_{s c a t} = \sum_{n = 1}^{N} a_{n} g_{n}$

I have modeled a probe-fed microstrip patch antenna and I want to extract the discretized current on the patch surface (i.e., the weights ( $J_{s c a t} = \sum_{n = 1}^{N} a_{n} g_{n}$ ) and the triangular basis function ( $J_{s c a t} = \sum_{n = 1}^{N} a_{n} g_{n}$ ) that approximates the current on the patch). What is the procedure to do it?

Thank you so much in advance.

Dear AGirlHasNoName

I believe that this equation is used to described Feko's MoM implementation conceptually. I not not think that the weights and basis functions are actually available directly for export.

When selecting the option to "Export to the Feko *.out file" for Geometry under the Feko tab of the "Solver settings" in CADFEKO you will get more information on the mesh triangles and the edges between them - to which the basis functions are applied. Maybe this could be of use to you.

Kind regards,

Johan H
