Re: Strange behavior from rectangular waveguide
Hmmm. Looks like nobody has an idea or a tip.

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

Re: Corrugated Horn Antenna Tutorial for openEMS
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
];

Re: Waveguide adapter simulation
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...

Re: Corrugated Horn Antenna Tutorial for openEMS
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...

Re: Waveguide adapter simulation
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?

Waveguide adapter simulation
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...
