Webε is the Fourier transform of the dielectric constant, k is the wave vector of the field, ρ ind ( k) is the Fourier transform of induced charge density, and φ ( k) is the Fourier transform of the total potential. The physical consequences of one part of this formula are easy to see. Since one part of ε is proportional to 1/k 2, ε is ... Web8. Dielectric constant below transition temperature 485 9.
