Port Boundary

Hello, all

Does the port in wave optics absorbs all the incident power ?

for example, I have two periodic ports. Port#1 is ON and port#2 is OFF. The electric mode field amplitude of the port#1 is (0,1,0). I want to read the Transmittance of power to port#2. So I want to read abs(ewfd.S21)^2.

What electric mode field amplitude I should set to the port#2 ? Does it matter for the listener port (=port#2) ?

Thanks !
