Dear all I tried to define a infinite plane-wave source with the function continuous_src_time() in a 3D volume which is repetitive in Y,Z two directions. The source plane is in YZ plane and I hope to define the infinite plane-wave propagating in X direction. But when I check the component Ey in different positions of the same YZ plane, the values are different and this means apparently the wave is not a infinite plane wave in the YZ plane. I think it is the problem of the boundary condition in Y and Z directions. But I have no idea how to define the repetitive boundary conditions for a infinite plane wave.
Thanks!
