The solid-state characterization technique using dual-comb spectroscopy was applied for a split ring resonator, which is a typical metamaterial. From the Fourier analysis of the dual-comb interference signal, the complex transmittance spectrum characterization of the sample in the near infrared region was demonstrated.
