+## solprop

+The pulse-propagation code [solprop](https://github.com/LupoLab/solprop) is the worked
+example of this interface: it takes its gases, gas mixtures, glasses and metals from
+optmat. Its manual shows the other side, in [Materials](https://solprop.readthedocs.io/en/latest/guide/media/materials.html),
+[Material selection](https://solprop.readthedocs.io/en/latest/guide/media/material-selection.html) and
