Interference in Rotating Structures and Metamaterials

Using the formulation of electrodynamics in rotating media, we study the effect of rotation on complex interference and diffraction patterns of metamaterials and/or periodic structures, as observed in the rotating medium's rest-frame. The interference is generated by a set of electrically small scatterers. To observe the rotation footprint, we use Green's function theory in rotating medium. Semi-analytic approximations for the rotation-induced pattern distortion are derived. The potential use of metamaterials for enhancement of rotation effects is studied and discussed.
