Problem Set #1
Problem 1. the gap plasmon modes in a metal-insulator-metal structure (MIM) are similar
to the thin film modes (IMI). Please use the similar approach to solve a typical gap
plasmon system (MIM):
Please derive the equations that govern the different modes. Show essential steps of
your derivation.
Use the derived equations and real materials (Au-SiO2-Au) to plot the dispersion
curves of the odd and even gap modes with a numerical tool such as Matlab. Explain why
there is no cut off for the fundamental mode. For Au permittivity, you can refer to . B.
