Homework Help: Inhomogeneous electromagnetic wave equation

  1. Apr 12, 2010 #1
    1. The problem statement, all variables and given/known data

    Hey guys.

    I'm trying to get to the inhomogeneous electromagnetic wave equation for the magnetic field, this is what I've done so far

    My problem is that I don't know how to express the expression I marked in red with the magnetic field so I'm pretty much stuck on this one...
    can I please have some help?

    Thanks a lot.

    2. Relevant equations



    3. The attempt at a solution
