ADS Terminator component in transient simulation
It seems that the reactive part of TERM component is ignored by ADS in transient simulation.
I simulated a very simple schematic:
the Term component here is a complex load.
However, the simulation result shows that the voltage and current are in-phase to each other, that means the reactive part of terminator is ignored
as can be seen, the magnitude of load voltage is 2.0V, and the magnitude of load current is 0.04A, so the effective load is 50Ω, not (50+j*100)Ω.
So, in order to get reactive phenomenon in transient simulation using ADS, you should explicitly add one of the two reactive components.

voltage wave amplitudes & normalized voltage wave amplitudes
we should first define Vinc and Vref in such a way that their sum is the voltage, and their difference (divided by reference impedance) is the current..
then the definition of Vinc and Vref (in terms of V0 and I0) comes naturally.
for normalized voltage wave amplitudes:
