Terahertz gas sensor based on absorption-induced transparency

Terahertz gas sensor based on absorption-induced transparency

A system for the detection of spectral signatures of gases at the Terahertz regime is presented. The system consists in an initially opaque holey metal film whereby the introduction of a gas provokes the appearance of spectral features in transmission and reflection, due to the phenomenom of absorpt...
