You may have measured or acquired only the S11 values of a diode.

Find the other S-parameters (such as with the included matlab code),

and create a text file that has 2-port S-parameters as shown on the

next slide.

S11 = reflection coefficient

S21 = 1+S11

S22 = reflection coefficient (1+j0 for a diode)

S12 = 1 + S22 (or in this case, for a diode, it is zero)
