Dear Meep users and Meep Experts: Among the constants that one can use to define new output functions in meep are Dielectric and Permeability that are properties of the material objects in the simulation. Is it possible use other material properties such as the D-conductivity as constants in output functions?
A problem occurs if one is simulating dispersive materials characterized by a fitted Drude-Lorentz polarization model. The fitting parameters actually available in the literature for the common metals such as Ag and Au assume a value for the real part of epsilon equal to unity. Calling the epsilon output function, output-epsilon, creates and h5 file with a map of the real dielectric constant in the computational space, and therefore output-epsilon makes no distinction between vacuum and the dispersive material. This problem could be avoided if one were able to use some other material property like the D-conductivity or the value returned by the Drude-Lorentz susceptibility. Is it possible to access these properties and construct a field function with them?
