Figure 4

Transmissions of the two metamaterial samples and the lactose film.

Frequency-dependent amplitude transmission of (a) the SRR and (b) the hole array samples. Red curves are the results measured by the proposed THz-TDS system while black curves are those measured by FTIR. (c) The amplitude transmission of the lactose film deposited on a silicon wafer. The absorption signature frequencies have been marked.
