Wave equation

  1. Mar 11, 2008 #1
    1. The problem statement, all variables and given/known data

    I need to solve the following wave equation:
    [\nabla^2 + \frac{\omega_a^2}{c^2}\epsilon]\mathbf{E_a} = -\frac{4\pi\omega_a^2}{c^2}\mathbf{P}^{(3)}

    2. Relevant equations


    E_1 and E_2 are two electric fields with different frequencies.

    3. The attempt at a solution

    I'm not sure how to attempt the problem. A starting point would be good.
