Homework Help: Function profile of toothed and plane parallel plates, then fourier transform.

  1. Dec 5, 2007 #1
    I want to write the dielectric profile of the following system, so I can then write its fourier transform as an integral...


    The plates are semi-infinite.

    So far I have:

    Epsilon, for: -infinity < z <= 0

    1, for: 0 < z < ?

    Epsilon, for: ? <= z < +infinity

    I need to find the expression given by ? to complete the profile but have no idea how given that its not continious. That will do for now. Any help would be much appreciated. Thanks.
