Hello everyone!
I am modeling a waveguide with the purpose of verification, but I am getting high errors in amplitude when the length of the waveguide is not a multiple of the wavelength of the propagating wave (when it's a multiple of the wavelength it converges to analytical solution).
I am using the scattering boundary condition and it should be transparent to the radiation in this case, but it looks like part of the wave is being reflected because the amplitude is bigger than it should be. Anyone had a similar problem or can explain this?
Thank you in advance!
