Homework Help: Deriving Conditions for D field

  1. Sep 1, 2005 #1
    Hi there,

    I was wondering if anyone would be willing and able to help me with this question.

    Q. Derive the boundary condition satisfied by D at the interface between 2 media.

    I know that the D field is continuous at the suface, but I need to be able to derive this.

    If anyone can help I would be really greatful

    Thanks alot in advance

    You need to be able to derive that the magnetic field is continuous? I would think that something like continuity would be the original assumption in deriving other outcomes. Are you trying to derive the boundary conditions, i.e. transmitted wave, reflected wave at a dielectric interface?

    The question stated is a question on a past exam paper, I am trying to review these questions.

    I need to derive the boundary counditions satified by D at the interface between 2 media

    Please help
