Effect of multipole interaction on the absorption spectra of small spherical particles near solid surfaces
In electrostatic approximation the interaction problem of electromagnetic radiation with an ensemble of small particles near to flat surfaces (surfaces of solids, interfaces, surfaces of biological membranes, etc.) is solved. The response of electrodynamic system: a small spherical particle (nanopar...

Surface| Zusammenfassung: | In electrostatic approximation the interaction problem of electromagnetic radiation with an ensemble of small particles near to flat surfaces (surfaces of solids, interfaces, surfaces of biological membranes, etc.) is solved. The response of electrodynamic system: a small spherical particle (nanoparticle) – substrate in external electromagnetic field is determined. The algorithm of problem solving is elaborated in general case multipole interaction in the system. Analytical solutions to cases dipole - dipole and quadrupole - quadrupole interaction are founded. The frequency spectrums of scattering, absorption and excitations is analyzed, and gold and silver particles on gold and silver substrates correspondently are analyzed. The big number of graphics and tables is presented as an illustration of elaborated approach. |
