Hello,
I want to simulate propagating modes traveling in some curved waveguide structure;
FDTD has "mode source" for that, is there somthing similar for DGTD?
All I could find is plane waves and Gaussian.

How can I inject a 2D mode profile into DGTD ?

Hi Amit,

That is correct. The DGTD is a relatively new solver and therefore doesn't have all the features typically required for PIC simulations. I believe they will be included over time but at the moment you will have to use either FDTD/MODE to inject/simulate a guided mode.

Is there a workaround or hack i can implement to control the injected field?

Hi Amit,

I don't there is. But let me double check internally and get back to you on this.
