active s is the reflection coefficient of one port when another port is excited...
for example, a 2 port system ,the total reflect wave at port 1 is S11*V1+S12*V2
the total reflection coefficient is total reflect wave at port 1 over total incident wave at port 1,then reflect coefficient is (S11*V1+S12*V2)/V1,which is the active S(1:1) |
