Field calculator HFSS

How can i write this equation in the field calculator of HFSS:

Where Pc represents the conductor loss.

I tried to get it for you, but HFSS seems to compute tangents in some strange way that involves lines and not surfaces. I know that HxH* is ComplexMag(CVec_H) (squared), and integrating over a surface you just have a ComplexMag(CVec_H) (squared), select geometry, select your surface, then press the integrate button.

Some more research is required....I'll let you know if/when I get it.

Dear PlanarMetamaterials, thanks for the response, i've found the solution.
the method is given in page 21 of Field Calculator Cookbook v12 of HFSS.
