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?
