(a) Transmittance spectrum of the metallic nano-slits structure in the working frequency range. (b) Transmittance spectra of lactose and maltose on the quartz sheet and metallic nano-slits structure. The enlarged views of the transmittance spectra of lactose (c) and maltose (d) on the quartz sheet around their characteristic frequencies of 0.529 and 1.12 THz. (e) Transmittance spectra of a mixture of lactose and maltose on the metallic nano-slits structure.
