WebIn microwaves, we often refer to relative permittivity as the "dielectric constant". These terms are interchangeable, but "relative permittivity" sounds more scholarly if you want to pretend to be a nerd. Saying "relative dielectric constant" is like Yogi Berra saying "deja vu again". Quite often dielectric constant is referred to as "DK" or ... WebThe dielectric constant is always greater than or equal to 1.0. This means the E-field in Equation [2] is always reduced relative to what the E-field would be in free space [Equation 1]. The permittivity is a measure of this reduction. The permittivity of common materials is given in Table 1. TABLE I. Common Values for the Dielectric Constant.
