Welcome to the LSPR-glass-transmittance wiki!

The project is all about modelling the Localized Surface Plasmon Resonance (a.k.a. LSPR) transmittance under visible light illumination.

It's mainly created for fun, but aims at bringing some complicated physics to a point when everyone can play with control handles, e.g.:

  1. glass matrix
  2. metal type in nanoparticles
  3. size, size distribution
  4. concentration

Formulas for absorption and scattering cross sections in plasmonic resonance are taken from 1.

1 Optical Characterization of Single Plasmonic Nanoparticles - J. Olson, S. Dominguez-Medina, A. Hoggard, L.-Y. Wang, W.-Sh. Chang, S. Link; Chem Soc Rev. 2015 January 7; 44(1): 40-57. doi: 10.1039/c4cs00131a.

This is also my first "by-myself" project, so please excuse any mistakes.

But should you find any, do please report them back, so it can be corrected!
