In contrast to this surface plasmon theory, in which the central role is played by collective electron density waves propagating along the surface of metal films in a free electron gas model, the authors of paper [5] propose that the surface metal-air medium should be regarded as a metal skin and that the ideas of the Richardson-Dushman effect of thermionic emission are crucial [6].
