In a dielectric medium, the charges are not free to move around, so electromagnetic waves are slowed down a bit, but otherwise can freely propagate.
In a metal, some of the electrons can move around, and thus tend to absorb and/or reflect electromagnetic waves.
But at the interface between a dielectric and a metal it is possible to have a mode that is part electron oscillation and part electromagnetic field, travelling along the interface, known as a "surface plasma polariton" (sometimes abbreviated as "plasmon").

Shown in the animation is the electric field (which is a vector quantity, hence the arrows).

Ultralight plasmonic structural color paint - researchers looked at how nature produces colors without pigment, and the result is a new, plasmonic paint. It uses colorless aluminum and aluminum oxide & the color comes from the geometric structures of the material, with light interacting differently with each structure to result in various displays. The lightest paint in the world, 1.3kg could cover a 747.
