Hello,
Im trying to calculate the power desipated in the silicon layer. So Im using surface integral in derived values, as power is intergral of E^2.
I changed the expression from 'Electric field norm' i.e emw.normE to emw.normE^2, does this approach give the correct values of power ?
And other case is Ive changed the expression to 'Total power dissipation density' that is the module itself, It has the units 'W/m'.
The latter sounded good for me, But want to check in before hand.
Please clarify me.

I'm not sure what dimension problem you are working in. Regardless, power dissipation is not simply E^2. Integrating "Total power dissipation density" over the volume, area, or edge in question (depending on the dimension of your problem) sounds like a better choice to me.
