Magnetic response induced by a moving dielectric slab

Magnetic response or magneto-optical effect is generally caused by the interaction of light with magnetized materials or some metamaterials. In this work, an exact solution for the scatterings of electromagnetic wave by the homogeneous dielectric slab moving in an arbitrary direction is presented. We find that the magnetic response can also be achieved by the dielectric slab moving along some certain directions. Such a kind of magnetic response depends on many factors such as the moving velocity of the object, the thickness, and dielectric property of the slab. At some certain velocities and incident directions of the wave, a complete polarization conversion of the reflected wave can be obtained. This means that the polarizations of the electromagnetic wave can be manipulated through reflections by the moving dielectric materials.
