Hi, I turned on the filter but the problem is still there. You can see the figures below. I have two out-of-phase dipole sources and the source wavelength is 900~1100nm. The chosen monitor(right figure of structure) is 1um away from the bottom of the parabolic structure. It shouldn't be just T_far2, but T_far1 shouldn't be negative. Can you check the problem again?
