mask on the wave field about smilei HOT 5 CLOSED

Hi
The Silver Muller boundary conditions are written to be optimal for either the plasma or laser frequency (not antenna) and for normal incidence only. We are currently working to allow the user to define these parameters himself since we noticed that it can dramatically improve some particular cases. This will be available in the next release and might be enough to solve your problem.
If you share your inputfile we could try to confirm that this will fix your problem or not.

@beck-llr Thanks for your response. In order to confirm if the new feature solves my problem, here I attach the input file.

Hi
A quick run of your case without particles doesn't show any reflection (this is By). I guess your problem is related to the reflective boundary on the particles. You should maybe try the "thermalize" boundary.
Let us know how that goes.

@beck-llr
I tried the "thermalize" boundary condition but the reflecting waves did not go away. The field pattern is similar to the figure I showed above. (I note that the thermalize boundary only work for non-relativistic temperatures. So only the warm species is used in the run.)

The wave has a normal incident on the xmin and xmax border so adjusting the angle won't solve the problem. We are going to try to adjust the frequency of the absorbing boundary but we do not expect this to work either since absorption is correct in the absence of particles.
If you want to implement new boundary conditions, you can have a look at those that are already implemented in the directory src/ElectromagnBC/ and follow the same pattern. Do not forget to add your new BC to the factory in ElectroMagnBC_Factory.h.
