1. The ratio of the magnetic permittivity of a substance to the permittivity of a vacuum.

Example Sentences

"The high-pressure phase obtained this time confirmed the presence of a polar structure from the observation of second harmonic generation of the same strength as potassium niobate, and a relatively high relative permittivity was also obtained. As for the dielectric constant, it is expected that values equal to or greater than those of potassium niobate can be obtained by increasing the sample density, as predicted from theoretical calculations," says Prof. Yamamoto.
