WebDielectric constant is the ratio of the capacitance formed by two plates with a material between them to the capacitance of the same plates with air as the dielectric. For low megahertz, frequencies are less than are equal to 1,000 MHz. For high megahertz, frequencies are greater than 1,000 MHz. WebMar 5, 2024 · Dielectric constant (3.44) κ ≡ 1 + χ e, which is sometimes called the “relative electric permittivity”, but much more often, the dielectric constant. This parameter is very convenient, because combining Eqs. (43) and (44), (3.45) P = ( κ − 1) ε 0 E. and then plugging the resulting relation into the general Eq. (33), we get simply
