Hi, thank you for posting your question. The answer is not that trivial, there's no direct way to get this information from a monitor. We typically get the amplitude/phase information by calculating the S parameters of the structure. The principle is described in Metamaterial S parameter extraction. We use a dedicated analysis group from the object library for this:

The phase is obtained from angle(S), and the amplitude from abs(S)^2.
