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:

Jscat = ∑angn

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 (an) and the triangular basis function (gn) 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
