unit:PERMITTIVITY_REL
  a qudt:Unit ;
  dcterms:description """
  The $\\textit{relative permittivity}$ of a material under given conditions reflects the extent to which it concentrates electrostatic lines of flux.
  In technical terms, it is the ratio of the amount of electrical energy stored in a material by an applied voltage,
  relative to that stored in a vacuum.
  Likewise, it is also the ratio of the capacitance of a capacitor using that material as a dielectric, compared to a similar capacitor that has a vacuum as its dielectric.
  Relative permittivity is a dimensionless number that is in general complex.
  The imaginary portion of the permittivity corresponds to a phase shift of the polarization $P$ relative to $E$ and leads to the attenuation of electromagnetic waves passing through the medium.
  $$\\epsilon_r(w) = \\frac{\\epsilon(w)}{\\epsilon_O}$$,
   where $\\epsilon_r(w)$ is the complex frequency-dependent absolute permittivity of the material,
    and $\\epsilon_O$ is the vacuum permittivity.
