This seems to be a FAQ. There is no way to specify the source power directly. The reason is that, for exactly the same current source, the output power depends on the surrounding geometry. What you specify in Meep is the amplitude of the current source. In order to normalize the calculation, what one should normally do is to run *two* simulations. The second one just has the source and whatever the source is supposed to input into (e.g. an input waveguide); you measure the power in this simulation and use it to normalize the transmission in the other simulation. See the Meep tutorial for several examples of this. Regards, Steven G.
