We introduce and demonstrate the concept of detuned electrical dipoles (DED) that originates from the plasmonic realization of the dressed-state picture of electromagnetically induced transparency in atomic physics. Numerically and experimentally analyzing DED metamaterials consisting of unit cells with two and three differently sized gold nanorods, we show the possibility of optical transparency characterized by enhanced transmission, reduced group velocity and propagation loss. The concept of DED is further applied to plasmonic sensing of the environment, demonstrating unprecedented sensitivity to refractive index changes by the utilization of scattering asymmetry. By the similar concept, DED metamaterials are designed to function as nanometer-thin wave plates in reflection.
