Noun
relative permittivity (plural relative permittivities)
for a substance, the ratio between its permittivity and the permittivity of vacuum
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
A low relative permittivity allows for higher-frequency usage. Source: Internet
It has also been used to refer to only the real component ε' r of the complex-valued relative permittivity. Source: Internet
The actual permittivity is then calculated by multiplying the relative permittivity by ε 0 : : where (frequently written ) is the electric susceptibility of the material. Source: Internet
The latter is expressed by a number called the relative permittivity (also known in older texts as dielectric constant). Source: Internet
The relative permittivity of a material for a frequency of zero is known as its static relative permittivity. Source: Internet
