Hi,
I'm trying to perform an honest assessment of the state of open-source software for simulations of plasmonic systems. For example, simulating the transmittance/reflectance off of an optical fiber with gold nanoparticles on it. What I'd like to do is get honest sense of how straightforward and accurately such a system could be modeled in commercial software vs. open source. How big of a disparity in terms of quality and power would you say there is between open source solutions like FDTD Lumerical, Comsol etc... vs. open-source tools for mie-scattering etc? Are there clear standouts in terms of open-source plasmonic simulation software that are heads and shoulders above the rest? How good of an approximation do you expect from effective medium theories vs. brute-force FDTD solvers for modeling biosensors in the lab, and so on?
If anyone could chime in with their personal experiences, or links to any relevant literature, that would help us a gerat deal! Thanks
MEEP is a very good open source alternative with detailed documentation. It's not as "easy" to get started on as Lumerical but it's effective.
As for simulating biosensors at the right level of approximation, you may have to test the results from FDTD vs any analytical calculations to make sure your trends are right before you dive in. Goodluck!

Thanks Prineha. I've known about meep but never used it. It's not a graphical application, right? More like a toolset for building applications?
Dear Adam,
maybe you have known that DDS CAT is also a very important open software package based on the DDA method.
best wishes
