Power direction and transmission box Integration time


#1

Dear all,

I have a question concerning the power direction monitor and same goes for the transmission box. The data recorded by the monitor, is it the peak power, or is it the integrated power over the whole simulation duration or some other time span?

Thanks a lot for your help!
Cheers,
Katharina

Dear @zeuner

If you do not use any apodization, which can be found from Edit tab of the monitor, monitor will capture the electromagnetic field for the entire simulation and then will normalize it to the input power so it will be the integration of power over the entire simulation.

Regarding the direction, if light passes the monitor along the positive x (or y or z) direction, transmission will be positive otherwise will be negative. You can read more about it in the link below:

I hope this answered your question.
Thanks
