WebbA theory of the electromagnetic field in moving, finitely deformed elastic dielectrics is developed. The equations for a weak field superimposed on a strong field and an arbitrary state of finite deformation are deduced. Webb23 aug. 2006 · A theory of dielectric relaxation is presented which relates the frequency-dependent dielectric constant to a truly single-particle correlation function. For a sample of suitable geometry, linear response theory is used to relate the polarization to a many-particle correlation function. This correlation function is shown to have the same form ...
