Hi,
I'm using HFSS to model a resonant cavity with a waveguide delivery excited by a 6kW wave port. I would like to calculate the power density (W/cm^3) at every point in the cavity as well as the total average power density.
I have tried using the energy stored in a resonant cavity equation:
Energy stored = 1/2*integral_volume(ep0*E*Econj)dV and it comes up 0.00104 Joules integrated over the majority of the inside dielectric (air). If I plot the energy distribution before I integrate I see the distribution peaks ~4 Joules/m^3 where the E field is maximum. Honestly neither of these numbers make sense to me by themselves and they also seem to contradict each other...
How can I calculate the average power density in W/cm^3?
Thank you
