Fresnel Equation：what does an observation port exactly mean?

In the tutorial, it says that port2 is an observation port, but what does an observation port exactly mean?
Notice that in the port mode settings of port2, the norm of E is still the same with port1, both are abs(exp(-i*k*x))==1, but I think it shoud be multiplied with the transmission coefficient t_p, because what port2 receives is a transmission wave whose norm should be smaller than the incident wave from port1.
Can someone help me?
Best regards.

I just figure it out!!
In the Port's "port mode settings", the key is the "mode", in other words, the wave number k. While the constant coeffient mutiplied before the exponential will be automatically matched.
You guys could check with your own simulation experiment, and it's really a simple experiment! Just try!
