The relative permittivity of a material can be found by a variety of static electrical measurements. The complex permittivity is evaluated over a wide range of frequencies by using different variants of dielectric spectroscopy, covering nearly 21 orders of magnitude from 10 to 10 hertz. Also, by using cryostats and ovens, the dielectric properties of a medium can be characterized over an array of temperatures. In order to study systems for such diverse excitation fields, a number of measu… Web• permittivity of free space: ε 0 = 8.854·10−12 Fm−1 • permeability of free space: μ 0 = 4π ·10−7 Hm−1 • velocity of light in free space: c 0 = 2.998·108 ms−1 • impedance of free space: η 0 = 376.7 ≈ 120π The electrical conductivities of some commonly used metals and liquids at room temper-ature are given in Table D.1. plots in dera bassi
