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.

### 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
];

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...

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.
