31. A charged relativistic particle crossing the interface of two media with different dielectric constants emits transition radiation. 32. That is, at an interface between two regions of dielectric constants ? S and ? H, respectively: 33. Is the dielectric constant of the medium. 34. The use of solvents with low-dielectric constants such as dichloromethane or chloroform can minimize this side reaction. 35. The number of water molecules adsorbed will cause a change in the dielectric constant of the sensor. 36. The Brewster's angle is when the signal is the weakest and is a function of the dielectric constant . 37. Where ? r is the dielectric constant of the dispersion medium, ? 0 is the double layer ). 38. At optical frequencies, in semiconductors the dielectric constant exhibits structure related to the band structure of the solid. 39. Another potential difficulty of the reaction field method is that the dielectric constant must be known a priori. 40. To see how thickness and dielectric constant are related, note that Gauss's law connects field to charge as:
