Attenuation in conductors

  1. Apr 6, 2009 #1
    1. The problem statement, all variables and given/known data

    I'm writing a school paper on the behavior of electromagnetic waves when they hit the interface between a non-conductor and a conductor. My question is if, in the case of partial reflection, it is correct to allow for both components of the wave vector (the wave is confined to a plane) of the transmitted wave to be complex (in the conductor, there is attenuation in both* directions, isn't it)?

    * Of course, if the transmitted wave is orthogonal to the interface there is only one direction to consider.

    If it is of any help, this is how I imagine the electric field vector of the transmitted wave (in the metal) should look: [tex]\textbf{E}_{0t}\exp i(k'_{xt}x+k'_{zt}z-\omega_t t)\exp(-k''_{xt}x)\exp(-k''_{zt}z),\label{17b}[/tex]. The ' and '' denote the real and the imaginary parts of the wave vector components, respectively. (Ignore the direction signs. What I wonder is if he basic idea is correct).
