Homework Help: Backward Impedance Matching

  1. Oct 19, 2016 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
    1) I determined the input impedance of the first transmission line (Zin1).
    2) I calculated the equivalent impedance (Zeq) of 50 Ohms and Zin1
    3) Found corresponding impedance of Gamma_s (Zs)
    4) I switched the position of Zs with Zeq
    5) Replaced Zs with its complex conjugate (Zs*)
    6) Found input impedance of Zeq at length -l2
    7) Set it equal to Zs*, solve for real and imaginary coefficients to get l1 and l2

    The equation turns out to be very complicated and I am sure there is easier way, please help. Thank you
