Homework Help: Plane Wave, Power Passing Through Copper Sheet

  1. Feb 4, 2012 #1
    1. The problem statement, all variables and given/known data

    See figure attached.

    2. Relevant equations

    3. The attempt at a solution

    See other figure attached.

    Am I correctly calculating the power that passes through the area given in i) at the surface?

    I'm not certain my expressions for,

    [tex]\vec{P_{2AV}^{t}}[/tex] are correct for the general case.

    Is what I have correct?

    EDIT: I feel like the aim of this problem has nothing to do with what my solution attempted to achieve.

    Isn't this a simple poynting vector problem that has nothing to do with incident, transmitted and reflected waves?
