I am confused about the Poynting vector Pz in Mode solutions.
If I set the material RI as a real number, the calculated real(Pz) for mode1 to mode3 are all 0,why?

If I use the material in library, the calculated real(Pz) for mode1 to mode3 have some values. But the power transmission along propagation for mode2 is a negative value, while that for mode1 and mode3 are positive. Why the sign of transmission for different mode is different?

Is it possible for me to normalize the transmission power for each mode to 1?
