I think I have it working. The answer was buried in the forum, but needed an extra bit of digging to work out how to add a delay to a lumped port. The simplest way is to add a Delay as shown below start = [feed.pos 0 0]; stop = [feed.pos 0 substrate.thickness]; [CSX port] = AddLumpedPort(CSX, 5 ,1 ,...

Hi all, I need to do some work modelling a GPS antenna(RHCP patch). Physically, this will be fed by a 90 degree hybrid to achieve the desired circular polarization. To simplify and speed up the simulation, I don't want to try and model and simulate the hybrid. I would like to excite my antenna via 2...

You will need to use paraView to visualise. Also, as the material is a volumetric solid, you will probably need to do some section cuts of the data to see inside.

You can view the discretized model using the Debug PEC option. https://openems.de/index.php/Model_Visualization.html There is a similar option for exporting dielectric materials. I can't find it in the online docs, but if you explore the runOpenEMS function in MATLAB the info there. Both export data...

Got it. Seems like the link from this page is wrong.

https://openems.de/index.php/OpenEMS#Installation

This link from the OpenEMS home page works.

There looks to be a problem with downloading the current windows build.

When I click the link..

I get..

Hi Thorsten,

The link you provided works.

If I try http://openems.de it automatically redirects to http://openems.de/index.php/ which is a blank screen on my device.

The main OpenEms.de site is still down for me btw. The forum working fine still.

Hi Thorsten, Good to have the site back up and running again. I have been using OpenEMS to design a log spiral antenna for amerture radio users. I have been documenting the development on my blog and hopefully pursuading some rf enthusiasts to give it a go. My blog is here https://hexandflex.com/201...

This has some similarities to a spiral antenna I have recently designed. See link for info https://hexandflex.com/2018/10/05/spiral-antenna-part-2-modelling-and-simulation-with-openems/amp/ First, my guess is cylidrical coordinates are better than cartesain for antennas like this. Though I confess i...
