A classroom theory of the surface plasmon polariton
Eur. J. Phys.
Surface plasmon resonance, also called the surface plasmon polariton, is an attractive illustration of basic electromagnetism. The investigation of this phenomenon in textbooks is often confusing for undergraduate students. The link between classical concepts of resonance and the solution of the problem is proposed in this work to clarify the procedure. The relationship with the course of solid state physics is proposed using the dispersion curves. The experimental setups are also mentioned.
