| 41. | In a nonlinear medium, the permittivity can depend on the strength of the electric field.
|
| 42. | Where is the electric constant, the relative static permittivity, and is the polarization density.
|
| 43. | Damping is achieved by the inherent resistance of the layers and the lossy part of permittivity.
|
| 44. | The magnitude of these normal vectors is given by the square root of the relative permittivity.
|
| 45. | Besides the relative permittivity, the size and number of layers determines the later capacitance value.
|
| 46. | The last set of calculations requires information on viscosity and dielectric permittivity of the dispersion medium.
|
| 47. | But my immediate concern then shifted to the issue of the measurement of the electric permittivity.
|
| 48. | :: : I find no great similarity between occurrences Vacuum permittivity and Speed of light.
|
| 49. | This material's permittivity above the plasma frequency can be positive and less than one.
|
| 50. | The quasi-conformal carpet cloak required anisotropic, inhomogeneous materials which only varied in permittivity.
