SubscriberI know the equation Lumerical uses for transmission is shown here
https://optics.ansys.com/hc/en-us/articles/360034405354-transmission-Script-command but when you solve for the Poynting vector what is the result? Does P = |E|^2?

Ansys EmployeeHello,
The equation for Poynting vector is given as: P=E×H∗

SubscriberHi Amrita,
Thanks for your answer. But what is the result of integrating the Poynting vector, since you are only taking the real part?

Ansys EmployeeHello,
The Poynting vector is integrated over the monitor surface to determine the total power through the monitor cross-section. The total power is then normalized to the source power to calculate the transmission.
More details can be found on the following page:
