Make a custom Sparameter.s2p file.
Step 1 : the Sparameter.s2p template file.
Step 2 : Open the Sparameter.s2p with a text editor.
Step 3 : Replace the value of the Freq., Mag., and Ang. with your device S parameters
Step 4 : Save the file and exit.
Step 5 : Browse and submit your new Sparameter.s2p file.

  

 
Introduction:



`"Scattering matrix"`

`[S]=[[S_(11),S_(12)],[S_(21),S_(22)]]`


`a _1 (l_1) : "incident wave at port1"`

`b _1 (l_1) : "reflected wave at port1"`

`a _2 (l_2) : "incident wave at port2"`

`b _2 (l_2) : "reflected wave at port2"`

      `S_12=| (b_1(l_1))/(a_2 (l_2))|_(a_1 (l_1 )=0) `
`"Reverse transmission coefficient with input properly terminated"`

`S_11=| (b_1 (l_1))/(a_1 (l_1))|_(a_2 (l_2 )=0) `
`"Input reflection coefficient with output properly terminated"`

`S_21=| (b_2 (l_2))/(a_1 (l_1))|_(a_2 (l_2 )=0) `
`"Forward transmission coefficient with output properly terminated"`

`S_22=| (b_2 (l_2))/(a_2 (l_2))|_(a_1 (l_1 )=0) `
`"Output reflection coefficient with input properly terminated"`
