These novel devices exploit a property called permittivity, which describe a substance's ability to transmit an electric field.
permittivity is conceptually similar to electrical conductivity.
Uncertainty effects on electrical conductivity and permittivity spectra.
Frequency and temperature dependence of the permittivity of fresh fruits and vegetables.
British Dictionary definitions for permittivity
noun (pl) -ties
a measure of the response of a substance to an electric field, expressed as the ratio of its electric displacement to the applied field strength; measured in farads per metre ε See also relative permittivity, electric constant
(pûr'mĭ-tĭv'ĭ-tē) A measure of the ability of a material to resist the formation of an electric field within it, equal to the ratio between the electric flux density and the electric field strength generated by an electric charge in the material.
