WebMar 5, 2024 · First, let us discuss the simplest problem: how is the electrostatic field of a set of stand-alone charges of density ρ(r) modified by a uniform linear dielectric medium, which obeys Eq. (46) with a space-independent dielectric constant κ. In this case, we may combine Eqs. (32) and (46) to write. ∇ ⋅ E = ρ ε. Web5.2.1.1 Dielectric Properties. Dielectric properties include dielectric constant and dissipation factor, in which the dielectric constant is usually used to describe the dielectric characterization of a material. The lower the dielectric constant (κ) and dissipation factor, the less energy is absorbed from an electric field.
