Nanoimprinted Quasi 3D Nanosquares Plasmonic Biosensor (LSPR)

Dear Respected Members,

My educational background:
B.Sc and M.Sc. in Applied Physics, Electronics and Communication Engineering.

My knowledge on COMSOL:
I just setup the COMSOL 5.0 in my computer, and I am very beginner in COMSOL.

My Goal:
My target is to fabricate a Plasmonic Biosensor in Nanoimprinted technique by using cleanroom facility. For this, firstly I want to develop and simulate a "Quasi 3D Nanosquares" model for Plasmonic Biosensor with the help of COMSOL.

My Queries:
Can anyone suggest me how can I develop myself in COMSOL environment for Plasmonic Biosensor's modelling and simulation?
