Interference in Rotating Systems

Abstract

Using the formulation of electrodynamics in rotating media, we study the effect of rotation on complex interference and diffraction patterns, 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 spectral representation in rotating medium and its efficient approximation. Semi-analytic approximations for the rotation-induced pattern distortion are derived. Numerical efficiency of the approximated Green's function usage vs. that of the full spectral representation are briefly discussed.
