Thank you for your answer matt. I dont understand however how the structure::add_polarizability function works. I mean, it sets the polarizabiliy everywhere in the calculation volume or just in some specifc region ? Is the sigma function responsible for it ? Lets say I want to have entire space filled with some normal material and then just a circle inside with a dispersive one. Can I do it with the add_polarizability function ?
