Dear all and Prof. Johnson, I have written a code that studies the polarization dependent scattering properties of a plasmonic nanodisks. As a test material I used gold from the material library included with Meep and everything works well. For the actual simulation that I am interested in I need to include the dispersive in plane anisotropic conductivity of single layer Black phosphorus.
As explained here https://www.mail-archive.com/meep-discuss@ab-initio.mit.edu/msg06578.html and in the meep FAQ the properties of dispersive 2D materials can be fitted with the use of the DrudeSusceptibility and LorentzianSusceptibility while defining the structure thickness as 1/resolution and multiplying the conductivity by the resolution. Can the same be achieved for materials that have in plane anisotropic conductivity? The difficulty I am having is that I am unware of how I can define these properties in Meep for a material like Black phosphorus that involves in plane anisotropy and requires a tensor to properly describe its conductivity. I was wondering if there is an available example or information that I may have missed. I apologize for taking your time once again and I am grateful for your help. Thank you for providing such an excellent simulation tool free of charge. Best wishes Nikolaos
