Mie scattering off plasmonic nanoparticles

Romain Fleury, UT Austin

This is a general model to simulate light scattering off plasmonic or dielectric nano-particles or spherical nano-structures. I computed the total scattering cross-section (SCS), absorption cross-section (ACS), extinction cross-section (ECS), radar cross-section (RCS) and differential scattering cross-section (dSCS) of gold nanoparticles in the near UV, visible and near infrared range. Material properties are taken from peer-reviewed experimental data (P. B. Johnson and R. W. Christy, “Optical Constants of the Noble Metals,” Phys. Rev. B, vol. 6, no. 12, pp. 4370–4379, Dec. 1972). The model can be used as a starting point to compute the absorption and scattering properties of more complicated structures or metamolecules, with broken spherical symmetry and several constituents. This model completes the tutorial file "Optical Scattering off of a gold nano-sphere", by providing efficient ways to compute the total cross-sections. The obtained results match analytical predictions based on Mie theory.



NB : Models compatible with COMSOL 4.3 and 4.3a are available.To visualize the results, you may need to run the file.

This model will be helpful to my research.
However,my computer can not open version 4.3a.

Can you provide the model in comsol 4.3 version?

Thanks a lot.

Thank u for your time

also this model can not open in my computer.
also please can u provide it in comsol 4.3 or 4.2 ?

Thanks in advance

I have posted a second version in 4.3. Feel free to leave a review after you use the file.

Thank you.

Kindly, if possible, could you provide the same in v4.2, as I've COMSOL v4.2.
Thanks a lot!

Thanks. The comsol 4.3 runs well in my computer.
