  1. Hi ZJS Of course. Let's say you solved a circularly polarized horn antenna and exported the farfields to *.ffe file. Then this *.ffe file can be used as a farfield source (in place of the horn's full model). This will be an exact representation (in the far field) of the original horn, meaning it will be circularly polarized.
  2. Hi The reference plane for plane waves is the origin.
  3. Hi Kuzi Please see the Examples Guide model A-02 of the lossy metal cuboid and dipole.
  4. Hi Leo You will set the conductivity to your material of choice. There is a media library as well that you can choose from, e.g. copper, gold, aluminium, etc. Then you must also specify the thickness.
  5. Hi Brinta Attached is an example of a SRR. This is on an infinite substrate and uses microstrip ports. It can also be solved on a finite substrate. There you would have to use either a wire port down to ground or an edge port. To see the difference between using finite and infinite substrates, see the example of the microstrip patch antenna in the Examples Guide. SRR_Example.zip
  6. Hi Leo See the ExamplesGuide model of the dipole and lossy metallic cuboid for how to construct a lossy metallic surface.
  7. It would be simpler to first get the design working with a simpler port construction, such as the edge feed. Attach the cfx. patch__concept_edge_feed.cfx
  8. Hi Marcus I see there are many parts in the geometry tree. For a continuous mesh to be generated, you must Union all the parts. Then you must set the appropriate Region and Face properties. I would also rather use a waveguide port.
  9. Hi SQG You adjust the variables created for the radii of the loops.
  10. Hi Marcus With the default solver, MoM, the model is not solvable - 3292 TByte is required. You can activate MLFMM, but still you would need around 4 TByte. The model is electrically very large, and RL-GO is suitable too. Attached is the model containing the RL-GO settings. 001_rlgo_.cfx
  11. Hi PnP You can use tools such as path sweep, spin and sweep. The video of the microstrip spiral inductor should help: https://connect.altair.com/CP/kb-view.html?f=2&kb=128345
  12. I don't have any advice other than to just try a couple of formats until you hopefully one works.
  13. Hi Sutton How many meshed segments were created? If the wire is meshed into a single segment it could appear to move. With multiple segments I would not expect this behaviour. Attach some screenshots or attach a sample cfx?
