Hi,
I am trying to determine scattering cross section of a silicon sphere. I have seen tutorials in which people have taken surface integrals of "emw.relPoavx*nx+emw.relPoavy*ny+ emw.relPoavz*nz". I want know- what is the difference between ewm.Poavx and emw.relPoavx?

Thanks in advance!

Regards

Nishant

Nishant,

ewm.Poavx is time average x-component of the Poynting vector of the total EM field.
emw.relPoavx is time average x-component of the Poynting vector of the scattered (or relative, in Comsol terminology) EM field.

Sergei
