Field imaging near to the surface of terahertz reflective optics using a vector network analyzer Open Access

A Vector Network Analyzer based quasi-optical measurement system, which 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 which 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

Other description
Dataset contains S-parameter measurements recorded with Vector Network Analyser Agilent N5224A. Data are stored as a Matlab v5 (*.mat) file. Complex values of the measured S-parameter are stored in a 101x101x11 (X*Y*Z) matrix.
