The interaction between electromagnetic resonances and its role in spectroscopic studies of molecules adsorbed on colloidal particles or metal spheres
We study the modification of optical properties of two metal spheres brought about by their electromagnetic interactions. We compute the excitation spectrum of the two sphere system and study the shape and the magnitude of the local fields. The relevance of this calculation to surface enhanced spect...

| Zusammenfassung: | We study the modification of optical properties of two metal spheres brought about by their electromagnetic interactions. We compute the excitation spectrum of the two sphere system and study the shape and the magnitude of the local fields. The relevance of this calculation to surface enhanced spectroscopy and to the study of the Brownian motion in colloidal solutions is discussed. |
