Abstract

This paper explores the use of a 1-D photonic crystal (PC), with and without a defect layer, for sensing in the THz spectral region. The PC consists of a stack of alternating high and low permittivity materials (BK-7 glass and air). Introducing a liquid or gaseous sample leads to a change in the transmission characteristics of the PC. An inverse problem method is used to characterize the dielectric properties of the sample under study. Such a configuration provides high sensitivity while requiring a small sample volume.
