WebThe dielectric constant - also called the relative permittivity indicates how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "the permittivity of a substance to the permittivity of space or vacuum ". ε0 = permittivity of vacuum or free space (8.854187817 10-12 C2 ... WebSep 12, 2024 · Here we consider only the physical (real-valued) permittivity, which is the real part of the complex permittivity (typically indicated as ϵ ′ or ϵ ′ r) for materials exhibiting significant loss. Permittivity varies significantly as a function of frequency. The values below are representative of frequencies from a few kHz to about 1 GHz.
