Hi, I'm simulating in the visible range with a characteristic size of 10nm.
I have: - cell with size (20 20) without PML. - PML along all directions with thickness 60. - Si3N4 (n=2) block, size (10 20), centered at (10 0) - Gaussian source centered at (-5,0) with size (0 (+ 20 (* 2 60))). When I run the system with component Ez I see strong reflections at block-PML interface, instead of PML absorbing the field. There're no such reflections at air-PML interface. How these reflections be avoided? Thx, David
