Difference of the magneto-electro-optical modulation depths ΔT/T for opposite directions of wave propagation normalized by the magnitude of the effect. Indices SiN and Au mark modulation depths for illumination of the silicon nitride and gold sides of the nanowire metamaterial, which are found to be identical within experimental accuracy. The transmission is modulated with an external electrical control signal of amplitude A=53 mV at different frequencies f in a static magnetic field |H|=130 mT and detected at the frequency of electric modulation. The magnetic field is directed perpendicular to the chevron nanowires in the metamaterial plane. Incident light is polarized perpendicular to the chevron nanowires at the wavelength of 1,550 nm.
