Nanoparticle heating with Surface Plasmon Resonance (SPR)

Hi Fellas,

I am trying to model heating of metallic nanoparticles when exposed to Laser/Solar light with Heat Transfer module. I am new to comsol and I do not now how to model the incident light and its interaction with NPs in this module.
The NPs are confined in a nanochannel and the surrounding liquid is water.

Can anybody introduce a similar simulation?

Thanks in advance.
