In FDTD the material property (refractive index or permittivity, permeability) fully determines the material. Please set or import its permittivity or refractive index at the dielectric state or the metal state while you are set the geometry. Here is a list of common material models: https://support.lumerical.com/hc/en-us/articles/360034394634-Material-Permittivity-Models
