Surface plasmons
metal’s free electron gas can sustain surface and volume charge density oscillations, called plasmon polaritons or plasmons with distinct resonance frequencies. The ex-istence of plasmons is characteristic for the interaction of metal nanostructures with light. Similar behavior cannot be simply reproduced in other spectral ranges us-

www.photonics.ethz.chspread out only slowly in the transverse direction. Examples are laser beam prop-agation or optical waveguide applications. In these examples the wavevectors k = (kx,ky,kz) in the angular spectrum representation are almost parallel to the z-axis and the transverse wavenumbers (kx,ky) are small compared to k. We can then expand the square root ...

Since core level electrons in solid-state atoms are quantized, the resulting energy spectra exhibit resonance peaks characteristic of the electronic structure for atoms at the sample surface.
