Hello,
This is a simple question about some tests I am doing about image theory and equivalence principle.
I have a directive antenna and compute its near-field in two planes z1 and z2 with z2>z1.
The planes are located in front of the antenna and the electric field is sampled lambda/2.
In another feko project I use the near-field from plane z1 as an aperture source to compute the near-field at z2 as described in the documentation.
The near-fields at z2 from the antenna and the aperture are very close to each other in magnitude and phase, they are the same.
Now, in another feko project, I create as many magnetic dipoles in the plane z1 as the number of points in z1 with same location and carefully oriented (x and y oriented considering orientation from equivalence principle, m=Exn). Then I copy the magnitude and phase from the efe file at z1 and compute the fields at z2.
This is I create the aperture with magnetic dipoles myself and the near-fields are different.
Can anyone explain me what can I do to have the same fields using the magnetic dipoles? Is it a scaling? Am I understanding something wrong?
