21. Signal degradation by loss tangent and dielectric constant can be easily assessed by an eye pattern. 22. Dielectric materials with giant dielectric constants can be fabricated as modified single, binary and perovskite oxides. 23. The decay constant is a function of the material's relative dielectric constant and its bulk resistivity. 24. While the densities and viscosities are increased, the dielectric constants , surface tensions, and refractive indices fall. 25. Dielectric constants lower than 2.0 have been reported.26. The dielectric constant of a material can be found by a variety of static electrical measurements. 27. Its dielectric constant is typically about ~ 25 although values of over 50 have been reported. 28. The addition of silicon to hafnium oxide increases the band gap, while decreasing the dielectric constant . 29. With a high dielectric constant ( 55 ) and high specific conductance, it is an attractive solvent. 30. They can be modeled from the viewpoint of an effective dielectric constant , or an effective surface impedance.
