Hi all,
I have design a horn antenna with a coupled metallic lens and the radiation pattern shows a bad Front/Back ratio that is confirmed in the animated fields visualization. Some ideas of why is this happening?? Could be the lens attached to the mouth of the horn that is modifying the...
Hi all,
It might be a silly thing, but I would like to do it in the proper way and don't know if it is even possible: Once your 3D model in CST is drawn, is it possible to export some views of the model? I want to have the outline of my waveguide as if it was drawn as a technical sketch.
Is it...
Hi all,
I was wondering if this is possible. I have modelled a 3d structure of a Horn antenna in CST MWS 2014 and the whole thing (with a considerable thickness in order to have screws through it and have a model easy to print in a 3D printer) is made out of gold. The thing is I just need the...
Hi all,
I have a big issue here with a curve I measured field phases along a line and I think you could give me a hand with this. I used a parabolical curve to measure the phases of an incoming electromagnetic wave along it, because I want to study how it arrives in a parabolic lens. But here...
Hello all,
I am starting to get badly anxious as I'm watching the progress bar in CST 2014 T solver. I reduced the accuracy expecting the simulation to end earlier, but transient analysis gets stuck in damn 99% and the countdown keeps rising.
Any hint why is this happening even to the lowest...
Hello,
I am working with CST 2014 and I am trying to simulate a rectangular lens coupled to a rectangular horn antenna with a little angle of flange in E Plane and a wider angle in H plane (close looking to a H-sectoral antenna) but the meshing in the aperture and in the lens is very dense, due...
More precisely, what I am intending to do is: Given a parabolic curve, create a parabolical-cilinder-thing, kind of a cube with a parabolical hollow in one face, but not 3D so you can see the parabolic curve from above and below.
I am afraid I didn't explain myself properly, but anyway, some...
Hello fellows,
I will keep it simple: I am trying to plot the parametric results of the farfield radiation diagram of a horn antenna on the same graphic. I mean, I am varying the flare angle so I get different s-parameters and so, but how do I plot a parametric view of the radiation diagram...
Hi,
I will try to explain myself: I am trying to record, frequency given, the power along a line (z axis) in order to find a focus for such frequency. The only field probes I find are the ones you use to figure out field strength for variable frequencies, determining the position x y and z for...
Hello you all,
I am stuck with a very little issue, so I hope you help me out, please:
I think I grasp the basics on using Eigenmode Solver, but still dont know how to plot the classical dispersion diagram of a unit cell (typical beta versus frequency) and I need it urgently to study negative...
