Permittivity of brass
WebIn electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε ( epsilon ), is a measure of the electric polarizability of a dielectric. A material with high permittivity … WebThe permittivity and dielectric loss are given by the Debye Eq. (1.57) (1.57) where ε 0 is the static field dielectric, ε ∞ is the high-frequency dielectric constant, and τ is the relaxation time. ε∗ = ε′ − jε″, ε′ is known as the dielectric dispersion and ε″ is the dielectric loss and is given by.
