    1. The problem statement, all variables and given/known data

    2. Relevant equations

    Pwr Ref Coeff:

    (Z'-Z)/(Z'+Z) all squared

    I maybe made a mistake but i cant spot it. And its bugging me
    I did square the whole thing afterward for the power...but i just have a sign error

    3. The attempt at a solution

    Please note that in negating one of my terms I underlined the wrong things, I did not negate u0/e0. but everything else in the demoninator cuz they are much smaller

    I don't know how to do the problem, but I do know that you made a mistake when you multiplied the numerator by the complex conjugate of the denominator. The i's don't go away for the numerator.
