A dynamical theory of elastic dielectrics

A 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. It is shown how certain electro- and magneto-optical effects and the retardation of a sound wave by a strong magnetic field in a dielectric can be explained and correlated. © 1963.
