- Do they actually look reasonable for a circular aperture? Going from the far field to the near field?
- No equations, qualitative question.
I feel like I am "exactly wrong" ; In the far field I get more variation in the same xy-space and in the near field I get less variation. I feel like the opposite would be true.
I'm trying to create a diffraction pattern by replacing the aperture with a thin cylinder with a uniform volume current parallel to the axis. This approach may not be theoretically informed, I'm just trying random radiation distributions.
Is my flux pattern even right for a uniform volume current (thin cylinder filled with uniform volume current parallel to the axis and flux pattern in a plane parallel to the circular faces of the cylinder)? I feel like it is not; I think the flux pattern should be more spread out in the far field as opposed to the near field but I'm getting the opposite of that.
