Homework Help: Surface Plasmon Polaritons at Metal / Insulator Interfaces

  1. Dec 15, 2012 #1
    1. The problem statement, all variables and given/known data
    we are considering the surface plasmon mode at the interface between a dielectric and a plasma. Solve explicitly for the TM mode and identify the relationship
    between dielectric and plasma permittivities that must be satisfied for the mode to exist.

    2. Relevant equations

    3. The attempt at a solution

    I am trying to solve for TM modes , but i can't relate the permittivities and it is becoming difficult to identify relation between those permittivities
