Is the dip of reflectance always caused by plasma?

摘要：

Surface plasma polaritons are collective electron charge oscillations localized at the interface between two different media with the real part of dielectric functions ε in opposite signs. The plasma resonance can be excited at the frequency to satisfy the condition in which electric displacement D = 0, implying that ε = 0. In this case, it is a longitudinal field inside the metal which does not obey the rule of wave-vector conservation for the photons interacting with electrons inside the metal.
