In the context of QuantumLaP Work Package 4: “Dispersion relations for surface functionalization”, I developed a numerical tool (in Python) to investigate the properties of Surface Plasmon Polaritons with a wide selection of materials and laser wavelengths.
Feel free to ask your access and to start a fruitful collaboration.
All details are presented here on the code repository.
