We can also relate waves at port 2 and port 2' through the electrical length that separates them,

This allows us to work out the transformation matrix shown below

which provides the relationship between S-parameters at two sets of reference planes.
Two-port S-parameters are an extremely important tool when it comes to transistor characterisation
and amplifier design, as we will see in chapter 5.
