Boundary Conditions in a Waveguide

  1. May 5, 2012 #1
    1. The problem statement, all variables and given/known data
    Derive the boundary conditions for the B field imposed by divB=0


    I'm lost with this question, I don't really understand how boundary conditions work. D.J. Griffiths only really mentions how to arrive at the conclusion that:
    B[itex]_{1}[/itex][itex]\bot[/itex]-B[itex]_{2}[/itex][itex]\bot[/itex]=0
    but doesn't outline the method enough so that I can understand it. Any help would greatly be appreciated, even if its just a link in the right direction to understanding the concept.

    Thanks
