WebDielectric Properties of Polymers. Polymers have long been known as insulating materials and are often used to insulate cables and electrical devices. They are also called dielectrics. Traditionally, dielectric materials are made from inorganic materials such as porcelain, mica, and quartz. However, polymers are also used as dielectric materials. WebThe dielectric constant of the material is related to polarization as p = ε0 (ε’-1) [6-8] where ε’ is the real part of dielectric constant, ε = ε’-iε’’ [9]. NDC represents polarization which opposes the applied field, similar to magnetic field lines expelled by diamagnetic materials [9]. The above condition happens when k ≠ 0 and ω → 0.
