Permittivity physics
Web𝑘, and led directly to a complex relative permittivity. However, this is not the only way to incorporate complex numbers (and hence absorption) into the equations. An alternate method is to use a complex conductivity instead of a complex relative permittivity. Typically either one or the other is done, but not both.

WebThe Coulomb constant, the electric force constant, or the electrostatic constant (denoted k e, k or K) is a proportionality constant in electrostatics equations. In SI base units it is equal to 8.987 551 7923 (14) × 10 9 kg⋅m 3 ⋅s −4 ⋅A −2. It was named after the French physicist Charles-Augustin de Coulomb (1736–1806) who introduced Coulomb's law. WebPermittivity (electric permittivity) is the ratio of electric displacement to the electric field intensity. It is a constant of proportionality between these two parameters. In the meter …
