Hajji, Maryam and Hammler, Jonathan and Zeze, Dagou and Balocco, Claudio and Gallant, Andrew J. (2017) 'Field imaging near to the surface of terahertz reflective optics using a vector network analyzer.', Applied optics., 56 (31). pp. 8746-8750.
A vector network analyzer-based quasi-optical measurement system that is suitable for mapping electric field intensity and phase near to the surface of terahertz reflective optics is presented. The system uses a fixed five parabolic mirror and transmitter/receiver head arrangement that has the benefit of requiring only the sample to be swept during measurement. The system has been tested with a micromilled aluminum zone plate reflector used as an exemplar structure. The measured focal point of the zone plate reflector, at its designed frequency of 1 THz, is shown to correspond well to both finite difference time-domain simulations and analytical theory.
