Abstract

The rest-frame electrodynamics of slowly rotating metamaterials is explored using the framework of polarizability theory and discrete-dipole approximation, developed to hold in the rotating structure frame of reference. A new class of rotation-sensitive metamaterials is defined and discussed. In contrast to the usual perception of a metamaterial as a structure whose electromagnetic measures of interest are related to spatially averaged or collective observations, we suggest new measures for rotation sensitivity that focus on selective inclusions or meta-atoms response. Multiple scattering supported by metamaterials play a pivotal role in establishing the materials rotation sensitivity. These new materials can be used as rotation sensors that may outperform the conventional Sagnac loop gyros. Thus, while multiple scattering effects usually hamper the Sagnac loop sensitivity, here they may suggest performance enhancement.
