Surface Plasmons An electromagnetic wave that can propagate along the surface of a metal complicates the observation of ordinary (bulk) plasmons. Let the metal be contained in the half space z > 0, z < 0 being vacuum. Assume that the electric charge density rho appearing in Maxwell’s equations vanishes both inside and outside the metal. (This does not preclude a surface charge density concentrated in the plane z = 0.) The surface plasmon is a solution to Maxwell’s equations of the form: Ex = Aeᶦᵠˣe⁻ᴷᶻ, Ex = 0, E, Beᶦᵠˣe⁻ᴷᶻ, z>
