Relative permittivity of plastic

WebJan 17, 2024 · The absolute permittivity of free space is approximately 8.85418782 × 10-12 m-3 kg-1 s 4 A 2. The permittivity of a dielectric material relative to that of free space is referred to as relative permittivity, usually symbolized by ϵ r, or dielectric constant. WebApr 29, 2016 · 2. The imaginary part of the relative permittivity accounts for absorption in materials. The refractive index can be defined as. n = ϵ / ϵ 0. Once you have this quantity, you're in a better position to start thinking about what happens when EM waves pass through a material. When loss is neglected ϵ / ϵ 0 and n are real, and the EM wave ...
