permittivity (plural permittivities)
(physics) A property of a dielectric medium that determines the forces that electric charges placed in the medium exert on each other.
Although skin effect limits Tesla currents to the outer fraction of an inch in metal conductors, the ' skin depth ' of human flesh is deeper than that of a metallic conductor due to higher resistivity and lower permittivity. Source: Internet
Because there is a lag between changes in polarization and changes in the electric field, the permittivity of the dielectric is a complicated function of frequency of the electric field. Source: Internet
A Low Cost Integrated Interface for Capacitive Sensors, Ali Heidary, Thesis, p. 22 Sensors can be constructed to detect changes in capacitance caused by changes in the relative permittivity. Source: Internet
; Electromagnetics : An isotropic medium is one such that the permittivity, ε, and permeability, μ, of the medium are uniform in all directions of the medium, the simplest instance being free space. Source: Internet
As a result, electromagnetic laws in SI require an additional constant of proportionality (see Vacuum permittivity ) to relate electromagnetic units to kinematic units. Source: Internet
A low relative permittivity allows for higher-frequency usage. Source: Internet
