The index of refraction of a material is only well-defined at a single frequency. Meep works at all frequencies; therefore, the index of refraction must be implemented in a frequency-dependent manner. Specifically, it is implemented as a polarization field. See http://ab-initio.mit.edu/wiki/index.php/Dielectric_materials_in_Meep Typically, the complex index of refraction is defined in terms of real permittivity (epsilon) and conductivity (sigma) at a specific angular frequency (omega).
