Band pass filter using ADS

I designed a Band Pass filter using ADS and i want to determine the value of L S and W. but first i want to calculate Zeven and Zodd. can any body help me? i want the equations fot them.

Calculating physical parameters can be tedious and erroneous by hand.Instead, you can use "Filter Design Guide" or "Passive Circuit Design Guide" of ADS.But if you would learn how to compute these variables , you should be adressed to textbooks.Because every filter structure has its own computation method and there isn't any universal unique method for all.
