I am searching for a software or package to simulate the plasmonic characteristics of graphene nanoribbons in mid IR range. The aim is to obtain extinction spectra v/s wavenumber for graphene nanoribbon array on a substrate (say, Si/SiO2). It has to be based on random phase approximation (RPA) according to which plasmon resonance frequency is expected to follow a
√q dispersion. I'd like to tune the parameters such as ribbon width, carrier density and spacing in the simulation. Looking forward for your valuable suggestions. Thanks!
Are you looking for commercial software, open source software, or to write your own codes?
In terms of commercial software, just about anything can do it. HFSS, COMSOL, CST Microwave Student, and Lumerical seem to be the most popular.
For open source software, make sure the package can incorporate the material dispersion of the metals. I keep a list of open source packages on my website here:
http://emlab.utep.edu/opensource.htm
If you want to write your own software, I recommend finite-difference time-domain
http://emlab.utep.edu/ee5390fdtd.htm
or finite-difference frequency-domain
http://emlab.utep.edu/ee5390cem.htm
These are the simplest to implement and will get you started.

The best software which are adopted for such complicated structured is the COMSOL Multi physics software, you should read the paper under the title:-
Comparison of electromagnetic field solvers for the 3D analysis of
plasmonic nano antennas
by
Johannes Hoffmann*a, Christian Hafnera, Patrick Leidenbergera, Jan Hesselbartha, Sven Burgerb
I will attach it to you to differentiate between the different Electromagnetic solvers.
best wishes
May be you can have at a look at this too... COMSOL

All the best !!!
I am looking for commercial software rather than writing one myself. So far it seems COMSOL and CST are most suitable. Thanks for your answers!
there are so manynumerical techniques such as FDTD, DDA , FEM and commercial software are available. DDA is freely online available technique.
