41. It is widely used in battery applications because of its relatively high dielectric constant and ability to dissolve electrolytes. 42. The properties under consideration are usually the conductivity \ sigma or the dielectric constant \ epsilon of the medium. 43. Thus the vacuum polarization depends on the momentum transfer, or in other words, the dielectric constant is scale dependent. 44. The equation for the ellipsoid is constructed using the electric displacement vector " D " and the dielectric constants . 45. A modified version of the Curie Weiss law applies to the dielectric constant , also known as the relative permittivity: 46. It consists of a " puck " of ceramic that has a large dielectric constant and a low dissipation factor. 47. Here ? and ?denote the dielectric constant and magnetic permeability of the medium that the conductors are embedded in. 48. There are many materials with lower dielectric constants but few of them can be suitably integrated into a manufacturing process. 49. Let us take a region in which dielectric constant and permeability may be functions of position but not of time. 50. For insulating materials, it is the ratio of the static dielectric constant divided by the electrical conductivity of the material.
