The linear permittivity of a homogeneous material is usually given relative to that of free space, as a relative permittivity εr (also called dielectric constant, although this term is deprecated and sometimes only refers to the static, zero-frequency relative permittivity). In an anisotropic material, the relative permittivity may be a tensor, causing birefringence. The actual permittivity is then calculated by multiplying the relative permittivity by ε0: Web11 apr. 2024 · By inserting Equations 20 and 21 into Equation 19, the “free-space,” electrical length can be calculated as: (22) Therefore, perfect isolation is possible for the single frequency points: (23) When assuming that the Equations 17 and 18 become identical and Equations 20-22 can be inserted.
