I am using coupler comprised of slot and strip waveguide as shown in image. I want to calculate power in strip and slot waveguide seperately at different device length (z). I got intensity from ewbe.Poavz at different points but unable to see any option of power. I tried integration of intensity but it is limited to domains only (not at all z and in two WGs seperately). Is there any way to calculate power in COMSOL? Thank You
