Hmmm. Looks like nobody has an idea or a tip.

Not at first glance for a beginner.
I use both directions, Tx and Rx mode. But now I see what you want to say.

Hello Paul
Thanks, then it is clear.

I found a typo in the middle of page 36.
"-wgl-10 is the location" -> -wgl+10
Here it is correct mesh.z = [-wgl-lambda_max-9 -wgl-1 -wgl -wgl+10 0 len(1:2:z_number) length+2*lambda_max+9
];

Last weekend I studied some openEMS scripts (again). A rect-to-rect transition should be able to do (or a cir-to-cir transition), that's an easy job. For a better understanding. I need only 1 port for a rec-to-cir transition, but which one? [CSX, port{1}] = AddCircWaveGuidePort( CSX, 0, 1, start, st...

Paul, thanks for this helpful tutorial. I am a little confused. Is the definition of the mesh.x really correct? BC = {'PML_8' 'PML_8' 'PML_8' 'PML_8' 'PML_8' 'PML_8'}; % boundary conditions FDTD = SetBoundaryCond(FDTD, BC); % Calculate lambda/4 at lowest frequency to use as distance to nf2ff surface...

Thanks for the hint.

My idea was to "join" both tutorial scripts for circular and rectangular waveguides. But there is the question with the mesh and ports definition. Both ends could be open waveguides, no coax feed needed.

Yes, that was the question. Hmmm, but how?

Hi folks I am a novice in openEMS and still trying to understand/modify simulation scripts. Until now I have modified scripts to simulate W2IMU dual mode horns. Has anyone tried to simulate e.g. rectangular waveguide to circular waveguide using a quarter wave plate adapter between? Or only a rectang...
