Non-normalized mode profile

      Mode expansion monitor in FDTD gives the normalized mode profile of selected modes. How can I get non-normalized mode profiles or mode power profiles?

      You can just simply multiply a constant to the mode profile. But usually it is not meaningful since the mode profile is solved from eigen value equation.

      If you want to know how much the mode fields in a total field recorded in a frequency-domain monitor, you can either use port, or mode expansion monitor to get the S parameter.

      You can refer to this article: Using and understanding Mode Expansion Monitors
