Computational resources for "Lorentz Resonance in the Homogenization of Plasmonic Crystals"

This repository contains all computational resources that were used for computations in the aforementioned publication.

All compuations were done with small C++ programs based on the deal.II finite element library, freely available at https://www.dealii.org and https://github.com/dealii/dealii. See https://www.dealii.org/current/readme.html and https://www.dealii.org/current/doxygen/deal.II/Tutorial.html for more information about how to install deal.II and run a program based on deal.II.

The repository structure is as follows:

sobek

This subdirectory contains the sources for a program computing the effective permitivity tensor with the help of the cell problem and averaging. Parameter files for two prototypical configurations (nanotubes and nanoribbons) used in the publication are located in the prm directory.

sobek-eigenvalue

This subdirectory contains the sources for a program computing the spectrum and associated coupling constants for the corresponding eigenvalue problem. Parameter files for two prototypical configurations (nanotubes and nanoribbons) used in the publication are located in the prm directory.

How to compile and run the programs

Both programs are written in the form of simple deal.II example steps, simply configure via cmake . and compile via make. After successful compilation an executable sobek is located in a run directory. Simply copy and rename one of the two example parameter files to run/sobek.prm and invoke the executable.
