Our interest in the anomalous physics and technology of metamaterials have led us to investigate several aspects of metamaterial technology and the fundamental physical reasons underneath their anomalous electromagnetic behavior. Anomalous phenomena and intrinsic limitations have been underlined and investigated in different metamaterial geometries.
