Abstract :
Design and testing of a THz sensor ultimately to be capable of operating from 0.068 to 8.1 THz are presented. Results for modular approaches in the mm and submm spectral regions are reported utilizing cavity-enhanced techniques. Investigations indicate ppq levels of detection for molecular species with 1.0 Debyes dipole moment.
