Homework Help: Determination of polarization for combination of linearly polarized vectors

  1. Sep 10, 2012 #1
    Question Source : Elements of Engineering Electromagnetics 6th edition by Rao. Page 202 problem3.30

    Three sinusoidally time-varying polarized vector fields are given at a point by

    F1 = 3^(1/2) * ax * cos(wt +30)
    F2 = az * cos(wt+30)
    F3 = [ 0.5ax + 3^(1/2)ay + 0.5*3^(1/2)az ] * cos(wt - 60)

    So, what is the polarization of F1 + F2 + F3?

    I don't know how to use The mathematical discription of elliptical polarization to solve this problem.


    I've tried to arrange and combine them in x,y,z component respectively...
