Electromagnetic wave phasor conversion

  1. Dec 3, 2016 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations


    3. The attempt at a solution

    So I was given the electromagnetic E field equation in phasor form and I converted it to sinusoidal form. Is it correct ?

    Also will it be a reflected wave since we have (wt+Bz) and not (wt-Bz) ?

    Also will it be circularly polarized since it is constant at all angles ?

    I don't see a problem statement here - just an assertion.
    Is that your working? If so, what were you asked to do?

    In your conversion - you are only including the real part?
    How can you tell if a wave is reflected without (a) a reflecting boundary, and, (b) knowing the direction of the incident wave?
    To check polarization - try checking where the E vector points at different times. ie. ##t=n\pi /2\omega: n=0,1,2,3\cdots##

    Yes
    No. The wave is traveling in one direction. Which direction?
    Let t=0 and graph your wave in the x-y plane as a function of the angle θ = 20z = 0, 30, 60, 90, etc. to 360. Should be obvious. Looking in the -z direction, is it CW or CCW polarized?
