11. Therefore, the dielectric constant ( and the conductivity ) has contributions from both terms. 12. Compared to other polymers the BCB has a low dielectric constant and dielectric loss. 13. Where is the dielectric constant of the electrolyte solution and is the vacuum permittivity. 14. Hardness, toughness, dielectric constant and many other properties are microstructure-dependent. 15. Addition of fluorine lowers the dielectric constant of glass. 16. Having a low dielectric constant is a significant advantage, 17. The coaxial resonators may make use of high-dielectric constant materials to reduce their overall size. 18. The materials used determine the substrate's dielectric constant . 19. Relative dielectric constant of water is about 73, compared to about 4 for common circuitboard materials. 20. The " flow-fill " technology produces an insulation with a far lower " dielectric constant ."
