PICS Master2 lecture, "Metamaterials and multiphysical couplings [solved with finite elements]"

Introduction to finite element modeling for waves and other physical problems with FreeFEM

Lecture notes (slideswithout movies) (complete with movies)

Installation notes (for Windows, macOS or Ubuntu)

• The official FreeFEM (or FreeFem++) page is here. A download link to the latest version is at the bottom of page. When on the github.com website, click the title with the latest version of FreeFEM to go to the releases; scroll down the page and select the appropriate installer for your system.
• (older version from 2020) Install FreeFem++ 4.6 https://doc.freefem.org/introduction/download.html and follow instructions from https://doc.freefem.org/introduction/installation.html#windows-installation for the 'how to use'. If on Windows, double-clicking the FF icon will open a file chooser from which you can select a .edp file to run. Try the examples in folder 'FreeFem++ 4.6 Examples' that should also be on your desktop.
• If you like, you can install FreeFem++-cs from https://www.ljll.math.upmc.fr/lehyaric/ffcs/install.htm. This is an integrated editor.
• To edit files you can use Notepad++ at https://notepad-plus-plus.org/downloads/. You can get syntax coloring following the explanations from Highlight syntaxing for ff++ in Notepad++.
• Coloring instructions for different source editors (Atom, gedit, Textmate 2, emacs) can be found here.

Plot instructions

To plot data files saved in text mode, you can use whatever software you prefer. I am giving two possibilities. Save all files in the zip archive to the same directory.

1. Using Matlab or Octave, you can try the attached file 'bs_plot.m' for the TE case and 'dispersion.m' for optical waveguides.
2. Using gnuplot (install from http://www.gnuplot.info/), open the file 'bs.plt' to generate the two png images attached.
