Permittivity, permeability and conductivity : these are the dielectric parameters of a material. You need to determine the permittivity of your material because this feature is what responds to electric fields. Unfortunately, it's not that easy to calculate precisely. What is your material ? Is it isotropic or anisotropic ? Does it respond linearly or non-linearly? All these questions rise from the fact the molecular structure of materials varies widely. You can't calculate it it but can do some simulations and have some acceptable approximations.
