We present a multi-layered frequency selective surfaces (FSS) exhibiting low losses for broad band spectroscopic measurements in THz frequencies. The intent is to replace existing samples holders (e. g. z-cut crystal quartz) with transparent metamaterial layers and increase measurement sensitivity. To enable multiband and broadband responses, a multilayered FSS is proposed, and thus suppress losses in a given range of THz bands.
