Webb26 aug. 2024 · In fact, when negative permittivity materials are put into practical use, the negative permittivity usually needs to be low and frequency-stable; that is, the absolute value of negative permittivity and frequency dispersion are both small, which is also called the low-frequency-dispersion weakly negative permittivity behavior. Webb10. The electric constant (also called the permittivity) of a medium is a measure of the medium's resistance to the formation of an electric field. The electric constant of a vacuum is given the symbol - and its value is 8.85 × 10 12 Fm-1. The electric constant is used in Coulomb's law to find the force
