Scattering by a cylindrical gold nanoparticle

Please login with a confirmed email address before reporting spam

I am new to Comsol. Please could anyone help with this simulation?

I am trying to simulate the scattering by a gold cylindrical nanoparticle of radius 60 nm and height 50 nm. My simulation is based on the Mie scattering model on another discussion page www.comsol.com/community/exchange/215/.

However, my calculated scattering cross-section (SCS) is clearly wrong since it keeps increasing with wavelengths, as shown in an attached png file.

The absorption cross-section (ACS) seems correct, and I would expect the scattering cross-section (SCS) to follow the same trend.

Note: ECS=Extinction cross-section and ECS_OT=Extinction cross-section from optical theorem
