Abstract
This study presents a three-dimensional near-field measurement system to measure surface waves using LabVIEW. The system is based on the capacitive coupling between metasurface and the electric probe, which is optimised to increase signal-matching efficiency. In order to realise three-dimensional near-field measurements, the scanner is composed of three-axis sliding rods and three stepping motors to drive the near-field probe. Especially, the double position/signal difference method is used to obtain a high spatial resolution. The system is controlled by LabVIEW to realise automatic measurement so that the electric magnitude and phase distribution can be displayed in real time. Finally, a spoof surface plasmon polariton coupling metasurface sample is measured by the system. The measurement results of surface waves are in good agreement with the simulation.
