Hi, Ken, I went through the Poyting's Therom one more time, and you are right that the Saverage = Re(SXconjugate(H)) is in the format of phasor. As any periodic inputs can be decomposed into sinusoids of different frequency, the Therom should be able to apply to all the periodic/quasi- periodic inputs.
I do think right now that there is a hidden assumption in Poynting's Therom: the changing E field only generates the M field with the same frequency; so does the changing M field, as the linear, homogeous medium is assumed.
So, seems to me that the average power is not a good enough measurement for a non-linear system.
Thanks.
