    1. The problem statement, all variables and given/known data
    Hi this is my first post I hope that my explanation is good.


    Now this is the explanation. Now I will provide the known values.


    So I start looking literature and some formulas to solve this and I found two different propagation constants. Gama and Beta.

    2. Relevant equations

    3. The attempt at a solution

    But even if I realize which one of these formulas to use I can't really understand why the dispersion equation is given if I'm not using it. Really need some insights here.

    I hope you can help me,
    Many thanks to you
