Abstract

Many polar gas molecules possess distinct transitions in the terahertz frequency range. In this work, we present the design and fabrication of foam based THz gas sensor. This foam structure is auspicious for use as an effective sensing material owing to its high porosity, greatly reduction in its transmission loss in the Terahertz regime. To optimize the efficacy of cellulose in gas detection, we evaluate the properties of these porosities constructed by different fabrication process.
